Pokey Knobbed

Still chugging along on the Pokey synth module FPGA code. Last night I finished the first draft of the A/D sequencer. The result: knobs work! Based on the current scheme, the sample rates should be:

Pitch inputs: ~40kHz each
Volume inputs: ~40 kHz each
Wave inputs: > 40kHz each
Aux input: ~40 kHz
Sample rate input: ~20 kHz

The pots are sampled in the single-digit kHz range.

Here are a couple quick audio demos:

Audio 1

Audio 2

I made these to check how the channels modulate each other at different settings. I’m just turning knobs on the front panel; there isn’t anything connected to the inputs yet.

    They’re not available for sale yet, but they will be. I’ll be doing a run of 25 in August/September. If you want me to reserve one for you, just e-mail me via the “E-mail the Developer” link on the right side of the blog pages. They’re going to be $400 when they’re ready.
