MIDI Control Surface

Sometimes, you just need a lot of knobs (or sliders, or buttons), and Syntien makes it really easy to get dozens of responsive, configurable knobs on the screen with a single tap.

In this demo, we'll define a fairly complex sound in SuperCollider with a bunch of different parameters – low pass filter cutoff, high pass filter cutoff, vibrato, index of modulation, how quickly the pan position changes, etc.

In Syntien, the configuration will be pretty simple. We'll add a

Keyboard, which tells SuperCollider which notes to pick from, and a Knob Matrix, which gives us 16 knobs by default that send continuous controller values on control numbers 0-15. The Keyboard works out-of-the-box for this demo. In the Control Options screen, we'll set the default value for the Knob Matrix to 0.

We'll also need a few buttons to control a few things via macros:

• A "flush" button that releases all notes on the keyboard

• A "touch knobs" button that outputs the current MIDI values for all 16 knobs

• A "reset" button that sets the value of each knob to 0
