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
eectively 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.
