# SuperDirt Voltage
|
|
|
|
A small set of SuperDirt synths and Tidal helpers to control modular synths. No MIDI required!
|
|
|
|
### Pitch, with scale quantisation
|
|
|
|
```
|
|
-- change notes per octave on each cycle
|
|
d1 $ pitch "0 10 8 1" # scale "<12 31 8>" # x 0
|
|
```
|
|
|
|
`pitch` allows a pattern of note values. `scale` sets the amount of notes per octave. The pitch and scale values will be converted to `1v/octave`. Both `pitch` and `scale` can be sequenced for some microtonal madness...
|
|
`glide` accepts a strengh (in semitones, relative to scale), a rate (in step length).
|
|
|
|
```
|
|
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
|
|
|
|
|
|
|
|
```
|
|
-- create ar
|
|
d4 $ trig "1 ~ 1 1" # ar 0 0.5 1 # 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, `adsr` 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.
