SuperDirt Voltage

A small set of SuperDirt synths and Tidal helpers to control modular synths. No MIDI required!

Pitch, with octave quantisation

-- change notes per octave on each cycle
d1 $ pitch "0 10 8 1" # octave "<12 31 8>" # x 0

pitch allows a pattern of note values. octave sets the amount of notes per octave. The pitch and scale values will be converted to 1v/octave. Both pitch and octave can be sequenced for some microtonal madness...

glide accepts a strengh (in semitones, relative to scale), a rate (in step length).

-- glide to pitch
d1 $ pitch "0 10 8 1" # scale "<12 31 8>" # x 0 # glide 12 0.5

Gate

-- sequence gate inputs
d2 $ gate "0 1 0 0 1 1 1" # x 1

gate will take a 0/1 pattern and return +5v signals for the 1 values. Use -1 if you need a -5v.

Voltage automation

-- create stepped automation
d3 $ volt "1 0.2 0.5 -0.2" # x 2

volt will allow you to sequence voltages however you like.

AR (Attack + Release)

-- create ar
d4 $ trig "1 ~ 1 1" # ar 0 0.5 # x 3

-- patternise adsr
d5 $ trig "1 ~ 1 1" # ar (range 0.1 1 sine) "<0 0.4>" # x 4

trig will create a trigger sequence, ar will generate a new envelope for each trigger. Both of these can be sequenced.

In the second example, the attack time would grow for each triggered envelope over course of the cycle.

Clock

-- clock cv output
d6 $ clock # x 5

clock will output a clock cv, which matches the bpm of your tidal project. You can slow / fast this as well.

How to use

These require a DC-coupled sound card.

Add the voltage.scd synths to your active SuperDirt synth definitions.

Evaluate the voltage.tidal definitions after starting Tidal. These can also be added to your Tidal startup file.

In the above examples, x maps to a channel on your audio card. If you have an 8 output audio card, the x will likely be 0-7. If you are using an aggregate device, please refer to your Audio settings.
