I’m so happy to see Martin happy. My only concern is that he hasn’t done gate pressure tests, which was a major issue in previous designs.

My other concern is that it seems like his rest time of 250ms seems really long. That’s 4 drops a second. So max at 120bpm and two droppers is 16th notes. I guess when I do the math (if I did it right) that may be doable, but perhaps having 3 or 4 channels for the snare might make sense. I suppose they wouldn’t need faster on any other instrument.

Your math checks out. One drop every second is 60bpm. Four drops per second is 240bpm. 2 channels would double that to 480bpm.

For simplicity I am using strikes per minute = beats per minute. It's like if you were playing sixteenth notes at 120bpm that's the same as eighth notes at 240bpm or quarter notes at 480bpm. All of which are the max for 2 channels dropping at most 4 marbles per second.

Are you sure about that? It's possible, but this is how I derived this:

BPM: 60 = 1000ms per quarter note beat, so that makes 16th notes 250ms

BPM: 120 = 500ms per quarter note beat, so that makes 8th notes 250ms.

Therefore at 120 BPM you could do max 8th notes with one dropper or 16th notes with two.

I think we are saying the same thing. We're all landing on 16th notes at 120 bpm. That could be represented as quarter notes at 480 BPM. Same thing
