0 to 127 will increase the time of voltage slide to the new note in the range from 0 to approximately 1 sec.
In the next menu that will appear after we choose Pitch scale output, we have to assign to which voice in
polyphonic mode
that CV output will belong to. Voices are calculating in the order they are pressed in the chord. The options are Voice 1, voice 2…
and up to voice 8. Choosing only voice 1 for certain MIDI channel will enable monophonic mode only. That means after pressing
another MIDI note during already pressed one, the new voltage of new note will be generated at that output. Choosing Voice
2 will enable polyphonic mode with two voices. After choosing that option, the second pressed note will be routed to that CV
out. It is important to notice that you may or may not output some individual voices. Or output their duplicated values in same
or other pitch scales. For example, choosing Voice 1 for CV1, Voice 2 for CV2 will create a duo-phonic setup. In the same way:
Choosing Voice1 for CV1 and Voice1 for CV2 will output same voltages for first pressed note which you may use as precise
buffered multiple to feed to different oscillators to obtain unison-alike effect.
Choosing the maximal voice number (even one from the list for certain MIDI channel) will enable the polyphonic mode with the
voices count of that voice number.
Using different pitch scales for different voices in polyphonic modes is also possible – you may create a whole polyphonic
setup with different oscillators you have wherein some oscillators may be scaled to 1v/oct, and other 1.2V/oct, or Hz/Volt.
2. Pitchbend
outputs the pitch wheel data send from appropriate MIDI channel. The output range is selectable either from
-5V+5V (the most left position of pitch bend gives the lowest negative voltage of -5V and the most right position gives the
h5V), /-2.5V, +/-1V and +/-0.5V. To obtain the highest resolution it is recommended to /-5V (10Vpp)
pitch bend resolution and then decrease it with an attenuator afterwards. Choosing smaller ranges will lower the resolution of
pitchbend from 12 bit (+/-5V) down to 11 bit (+/-2.5V) or to
~
9.7bit (+/-1V) or to
~
8.7 bit (+/-0.5V). In calm when the spring of
the pitchbend is in the middle position the output value is 0 volts.
3. Trigger
– is a short 1ms pulse signal when NOTE ON event comes from MIDI device or DAW. For polyphonic mode you may
allocate desired voice for trigger signal or choose
Trigger Any
(Uni/Bi) that will return a trigger pulse for any voice from the
chosen MIDI channel.
Trigger Uni
in calm returns 0 volts and when triggred the signal goes up to +5V.
Trigger Bi
in calm returns
-5 volts and when trigged the signal goes up to +5V.
4. Gate
– same as the trigger, goes up to +5V when a NOTE ON event arrives, however stays at +5V until a NOTE OFF message
arrives. Similarly,
GateAny
returns gate when at least one key (voice) is ON at certain MIDI channel. Same goes for TrigAny and
S-trigAny. Use it if you create a polyphonic setup with only one envelope generator/vca/vcf at the end. Or course you may use
gate from the first voice - i.e., the one that was launched first but gate any returns gate for any of available voices pressed.
5. S-trig
(switched trigger)
– used in old Korg and Yamaha synthesizers. Itself is same as Gate but inverted, i.e., returns
po5V when in calm and goes to 0V when NOTE ON message arrives and returns back to +5V at consequent NOTE OFF.
S-trigAny
works in the same manner as GateAny above.
6. Trigger Note, Gate Note, S-trig Note, Velocity Note
– return trigger, gate, inverted gate (s-trigger) or velocity correspon-
dently when corresponding event appears from appropriate selected MIDI note from the list (120 notes in total or Any note for
literally any note).
7. Velocity Uni/Bi
– corresponds to note’s velocity that is 0v (or -5V) at startup (or preset choose), and then changes and
remains constant at every NOTE ON message. ‘Bi’ stands for bipolar output, -5…+5V and ‘Uni’ means unipolar 0...+5V output.
Velocity corresponds to a certain voice. That means if you would like to have 4 voices polyphonic setup and you would like to
use velocity for your patch, you should allocate 4 CV outputs to transmit velocity for each of 4 voices.
8. Control Uni/Bi
– corresponds to Control Change value. Same as with velocity, it could be unipolar: from 0 to +5V, or bipolar
from -5V to +5V.
Shuttle Control has a 12 bit digital-to-analog converter that means all the voltage values at every CV output contain
~
4 thou-
sand values (4096 steps) for the full -5V/+5V range. Pitchbend messages by MIDI specifications are 14 bit (over 16 thousand
values) and sending (squeezing) them thru 12 bit DAC doesn’t feel that crucial for ears. In the opposite, Control Change mes-
sages themselves are 7 bit (127 values) and give audible 1-semitone ‘steps’ when controlling analog parameters, like a filter
or pitch sweeps. That’s why we invented the No Damn Steps In CC (NDSICC™) algorithm (patents pending). That means you may
interprete ordinary MIDI CC values into CV and all the changes will be smooth and without audible steps. At the same time it is
possible to make fast instant changes without portamento-alike effects.
CC smoothed (uni/bi) corresponds to the CC translation with smoothing, however CC stepped (uni/bi) corresponds to straight-
forward 7-bit stepped voltage output. Same as with pitchbend messages, choosing unipolar range for CC instead of bipolar will
lower the resolution at that CV output from 12 to 11 bit.
