QuantiZer manual

The QuantiZer is a digital processor driving high precision analog CV circuitry. In its input it takes

CV signals from Sequencers, LFOs, Envelopes or pretty much any other module that produces

CV signals, and, in less than half a millisecond, it outputs CV converted to western chromatic

scales to drive VCOs in a modular. Without QuantiZer conversion it is hard to dial in speciﬁc

notes in a musical scale, so the QuantiZer osets the voltage to match exact notes; therefore, the

QuantiZer could be called a CV-to-musical-note converter. The beauty of the QuantiZer comes

from the ability to add and subtract notes from the scale, transpose sequences, switch musical

scales, add portamento and much more all from the front panel, which makes for a creative tool

to control and adjust melodies as they play through the QuantiZer.

The QuantiZer can work in two dierent modes: Free Run, where CV input gets immediately con-

verted to the output, or Trigger mode, where CV input only gets converted when a trigger signal

is sent to the CLOCK input. Trigger mode is very useful to synchronize the conversion process

with other events in your modular, and it is also a great mode for experimentation by sending non

repetitive trigger signals.

This manual has two parts: the ﬁrst section has tutorials for using various features; the second

section has detailed information about the connections and functions of the module.

QuantiZer Basics PATCH 1:

Using the Keys or Slider to set Pitch:

- Patch the QuantiZer 1V/Oct OUT to the Z3000 1V/Oct In

- Patch one of the Z3000 waveform outputs to a sound system to hear it.

- On the QuantiZer click FORCE 0V, all lights will turn o and the QuantiZer will be forced to

output 0V

- Adjust the Z3000 to 65Hz or click the Z3000 yellow button once to turn on the tuner and

adjust it to show Note C2. The Z3000 is now tuned.

- Click on Force 0V again, and click on Keyboard until the KEYS function is on. The QuantiZer

is set to a CV keyboard, clicking on the notes on the right side will make the Z3000 play

this octave. Notice the QuantiZer will quantize the key selection to the active notes (green

lights) of that scale.

- Click on KEYBOARD again until the light of this section are o

- Click on SLIDER and set it to NOTES, play the slider, to hear the Z3000 play all 5 Octaves.

Using the Z8000 as CV source: (please see drawing in next page)

- Plug a clock signal into your Z8000 Up and Down Column Input

- plug the CV out from Z8000 Up/Down into the NOTE CV jack on the QuantiZer.

- Set the SLIDER lights to o,

- set KEYBOARD to SCALE EDIT.

- Program some notes on the knobs on the Z8000

- Start the Clock source and the notes are quantized and sent to the Z3000 according to

keys of the selected scale, the green lights are the active notes, red light is the currently

playing note.

- In SCALE EDIT mode add or remove notes by clicking on them to hear how useful it is to

adjust and play the QuantiZer that way.

- Click on KEYBOARD and change to TRANSPOSE to use the keyboard to transpose your se

quence by that amount. For example, pressing D will shift the sequence up two semitones.

- Click on KEYBOARD to turn its modes o, click on SLIDER and select TRANSPOSE, use the

slider to transpose the sequence.

- Click on SLIDER and select OCTAVE, use the slider to transpose the sequence in steps of 1

octaves.

- Click on SLIDER and select PORTAMENTO, bring the slider down and the start bring it up to

add portamento eect to the notes.

Tip: At any given time if you feel lost or wish to start over, press and hold the RESET button which

will reset the module to last saved settings.

Using dierent scales:

- Click on Major, then click on note F on the right side keyboard and the green lights will

change position to show the new selected scale, which might change in the sequence as CV

in is converted now to F Major scale.

- Click Major then Gb to hear the switch again, click on Minor then D; musical progressions

can be made by switching scales.

If the VCO tuning has gone o, click on FORCE 0V and readjust the Z3000 to read note C (65Hz)

then click FORCE 0V to get back to playing.

QuantiZer Basics PATCH 2:

When using patch 1 transposing and other functions might sound a bit glitchy, that is because the

QuantiZer is not synchronized to the Z8000 clock. To sync the quantization switch the QuantiZer

to Trigger mode.

- Click on KEYBOARD, select INPUT RANGE

- On the keyboard select Trig (it is on Note A) so its light is Green

- Click on KEYBOARD to go back to Scale Edit.

- The QuantiZer will not quantize notes anymore until we apply a trigger signal into the

CLOCK IN jack.

- Using a Stackable patch the same trigger signal that goes to the Z4000 into the CLOCK IN

The QuantiZer will now quantize when a trigger is sent. With this function you can select when to

quantize, so try experimenting with other pulse sources to see how creative this can be.

For example: use one channel of the Trigger Riot or Circadian to trigger the Z8000 cv sequencer,

another channel to trigger the Z4000 envelope, and another channel to trigger the QuantiZer,

each channel have dierent trigger timings, this can go really deep with unexpected very com-

plex sequencing. Follow the patch below

Note * : In Trig mode Portamento is not active.

QuantiZer Recording PATCH 3:

The QuantiZer can record and play back notes played on the keyboard; we call it the Sketch Pad.

You can create sequences up 512 steps with manual entry of notes. Lets give it a try.

- Plug a clock signal into the Clock In jack

- click on RECORD, the QuantiZer now start recording, the Record light turns red,

- Play the notes in time on the keyboard,

- To ﬁnish click on RECORD again, the red light will start ﬂash and the recorded sequence will

play back

- Hit the RESET and the sequence will reset to step 1, sending a Trigger into the RESET input

will control the reset externally.

- Click on RECORD again to stop recording. try recording again, this time use the slider to

Transpose or jump in octaves.

- To clear the memory hold down CLEAR until all lights turn o for a bit.

QuantiZer as Sketchpad for Circadian Rhythms:

The QuantiZer recording function can be made to follow the Circadian Rhythms time line preci-

sely. To do that patch a Tiptop SyncBus cable from the Circadian SyncBus out to the QuantiZer

SyncBus in. See drawing below.

Syncbus drawing:

- Setup the QuantiZer to receive SyncBus signals, click on KEYBOARD and select INPUT

RANGE, on the keyboard select Sync.

- On the Circadian Rhythms Click on Boss twice to make the Circadian the ‘boss’ of the

QuantiZer.

- Set a loop on the Circadian, for example a loop of eight presets,

- click RECORD on the QuantiZer the LED turns red, once the Circadian loops the QuantiZer

will detect that and ﬂash the led indicating recording started, it will automatically ﬁnish

recording and start playback when the loop on the Circadian restart. These notes are saved

in the QuantiZer memory and will play back only when that exact preset is playing. That way

you can add notes in dierent areas of the Circadian timeline.

- To clear the memory hold down CLEAR till all light turn o for a bit.

Connections:

Note CV: Input for analog Control Voltage to be Quantized. Three ranges are possible for

input: 0 to 10 volts, 0 to 5 volts and -5 to +5 volt

Scale CV: Input for CV control of the Scale

1V/Oct: Processed and Quantized output

Clock In: Clock pulse input for 5V triggers. There are three clock modes: 16th, DIN and DAW

Reset In: 5V input for Reset of the internal counter. This can either be a single pulse or DIN

Run signal

SyncBus: Two sets of multi-pin connectors on the back PCB. Use a SyncBus cable to connect

to other TipTop Audio SyncBus enabled devices like the Trigger Riot and Circadian Rhythm.

USB Port: A standard USB Type A port on the rear PCB to attach a USB Flash drive in order to

update the device ﬁrmware.

Controls:

Keyboard: 12 switches corresponding to the Western 12 note scale from C to B. There are 4

modes for the keyboard:

- Keys to directly output a speciﬁed note to the 1V/Oct output. This can be used like a stan

dard one octave keyboard.

- Scale Edit to select notes to include or exclude from the current Scale

- Transpose to input the amount of transposition in single note increments. For example,

pressing E will shift all output up 4 semitones (C becomes E, D becomes Gb).

- Input Range controls the settings for voltage range, Clock format, saving and more

Slider: a 40mm pot for inputting the following data:

- Notes outputs a quantized pitch directly to the 1V/Oct output. The entire 5 octave ranges

is available via the slider.

- Portamento sets the slew rate between notes. The slewed output is not quantized in

between the input notes for smooth pitch bend eects.

- Transpose inputs the amount of transpose from 0 to 12 semitones. The transpose amount

is in semitones.

- Octave shifts the output up from 0 to 4 octaves.

- Input range selects the input range: 0-5V, 0-10V and +/-5V

Scale selection buttons: Press once to enable the scale type and then select the scale using

the keyboard (for A minor press Minor button then the A button on the keyboard, etc). Avai-

lable scales:

- Major selects a scale corresponding to the Western Major scale.

- Minor selects a relative Minor scale.

- S1 is the ﬁrst bank of 12 user scales.

- S2 is the second bank of 12 user scales

Note that the Scale CV overrides the manual selection of a scale, so disconnect the Scale CV

input or send 0V to it.

Editing Scales:

- Change the Keys mode to ‘Scale Edit’

- Select S1 or S2

- Add or Remove Notes from the Scale

- Scales need to be saved using Save in the Input Range mode of Keys to be recalled on the

next power up

Record buttons:

- Record has three states:

- O where the Note CV is directly sent to 1V/Oct,

- On where the Note CV is recorded using the Keyboard and Slider

- Play where each clock plays recorded values from memory

Reset sets the record or playback to the ﬁrst position in memory

Clear erases all of the recorded values in memory when held

Force 0V disables all Quantization and sends 0V to the 1V/Oct output. This is used for calibra-

tion and tuning of 1V/Oct devices.

Display LEDS:

- Keyboard LEDs in all modes but Utility use Green to show which notes are in the current

Scale and a Red LED to indicate the current output pitch.

- Keyboard LEDs display the current mode for the keyboard. When none are lit the

keyboard does not modify anything

- Slider LEDs show the current mode of the slider. When no LEDs are lit the slider does not

modify anything.

- Record LED is O when recording is o, steady when Recording is On and ﬂashing when

Playback is running.

- Scale LEDs are solid for Major and Minor and ﬂash for S1 and S2

- Octave indicates which octave the current output is in

Tuning a Z3000 VCO:

- Connect 1V/Oct output of the QuantiZer to the 1V/Oct input on the z3000

- Press the Force 0V button. The output will be 0V from the QuantiZer.

- Change the z3000 display to indicate Notes

- Turn the Coarse and Fine tuning knobs until the z3000 display shows a C pitch (C0, C1, C2

etc)

- The QuantiZer and z3000 will now have a range of that note plus ﬁve octaves (ex.C1 to C6)

Transposing:

There are several methods of transposing a scale in the QuantiZer:

- Keys Transpose mode. In this mode the Keyboard is used to select the amount of transpo

sition upward in semitone steps. Selecting C is 0 transposition while B is 11 steps up.

- Slider Transposition mode. In this mode the Slider sets the amount of transpose from 0 to

11 steps up.

- Slider Octave mode moves the transposition up by 12 steps each octave.

Note that the Octave and Transposition are additive so transposing up one octave and 5

steps is a 17 step upward transpose. Also, the maximum output from the QuantiZer is

always 5 volts so upward transpose will necessarily reduce the number of available steps

output.

Portamento :

Portamento creates a glide between quantized values for more natural pitch bend type eects.

The slider in Portamento mode sets the length of the glide time from microseconds to a few

seconds. It is very important to note that when Portamento is used all Quantization is disabled

in order to generate the values in between the pitches. Internal math does attempt to correct

for errors but the output will not be as precise as without Portamento, and as the Portamento

time is increased the errors become greater.

Recording Using CV Sketch Pad:

The QuantiZer can record up to 512 16th note steps which matches the internal 16th note

memory of the Circadian Rhythm step sequencer. The QuantiZer will follow the Group/Preset

when using the Circadian as a master clock (‘Boss’) over Syncbus.

The QuantiZer can accept a variety of clock formats including SyncBus from other Tiptop Se-

quencers. The clock format is set using the ‘Input Range’ mode of the the Keyboard. Be sure

to read the following ‘Clock Formats’ section to understand which format to use.

The CV recorder is intended to run at tempos between 2 and 300 bpm and have enough reso-

lution to cover any notes values entered in that range.

Clock formats:

- 16th, a 4 PPQ pulse used by many analog sequencers. The Reset In with this clock format

is a single pulse that resets the internal counter to 0.

- DIN, a clock mode designed exclusively to work with vintage Roland TR/TB devices. The

clock uses internal delays to compensate for the slow processing speed of the early micro

processors. The Reset In is the DIN Sync ‘Run’ signal that goes high when playback starts

(which is also a reset) and low when the clock stops.

- DAW, a 24 PPQ clock similar to the DIN standard but without any delays and the Reset In a

single pulse which resets the internal counter to 0.

This is designed for use with synchronization with a computer DAW application.

- SyncBus, the interconnection designed by TipTop Audio to sync clock based devices. This

cable carries clock, reset and preset data in parallel. The clock runs at 96 PPQ which

eectively replaces the internal clock of a device with this signal. Sync accuracy is down

to the microsecond level, and devices change presets in sync as well.

SyncBus is highly recommended for use with the Circadian Rhythm. The QuantiZer will preci-

sely follow the Group, Preset and Step of the CR in this mode.

Recording can be done either manually using the Record button to start and stop, or by sen-

ding reset pulses to the Reset In to start and stop. Using Reset is highly recommended for all

recording to maintain sync on playback.

The Record button toggles between three states:

O - In this state the internal CV conversion is either ‘Free Run’ or ‘Triggered based on the

TRIG setting in ‘Input Range’ mode.

Record - CV values are generated using the Keyboard ‘Keys’ and Slider ‘Octave’ as controls.

Recording is done in real-time. The Record start and stop are governed by external resets.

Playback - Recorded CV values are played from internal memory based on the incoming clock.

The Note CV and Scale CV are ignored as are the UI features of the keyboard and fader. The

Record LED will ﬂash to the tempo of the clock in this mode.
