Trigger length expectations

I was testing out my Kickain yesterday in conjunction with the NerdSeq. The nerdseq has triggers of configurable length, starting with 5ms and working up in increments of 5 ms. I noticed I had to tweak this up (need to doublecheck the specific amount) in order to get the kickain to respond. Just wanted to confirm what the expected trigger length/height is (I didn't see it specified in the manual).

I've attached a beta firmware that should address this issue, let me know how you get on and we'll release it on the main site.

Hi Nicholas. Thanks for getting in touch. Kickain should trigger on a +3v input of 5ms, it’s near instantaneous but other electrical characteristics such as the overall impedance could alter this. I don’t have any actual data measurements on this so I’m interested in your experience using the nerdseq.

looking into this, I think we will can improve the trigger sensitivity in a future software update. The short delay is there to avoid double triggers but probably a bit on the cautious side at 5ms.

Please do! I did some tests with ADDAC104 triggered at same time as Kickain and with ADDAC104 audio routed through Kickain:

KickainLatency.wav

Both modules triggered from NerdSEQ. First four bars shows how the latency is (around 8ms!) next four bars has triggers to ADDAC104 delayed to compensate.

As for avoiding double triggers - why? Let the user decide how fast they want to trigger.. it might be cool to trigger at audio rates. Trigger at 3V on leading edge along with a couple of volts of hysteresis in trigger detection function is enough to avoid unwanted double triggering.

[edit] Did some experimenting with triggering kick as far into audio rate as is currently possible - it is indeed cool. [/edit]

Thinking more on this, I guess triggering on leading edge would maybe not work well in conjunction with the accent functionality?
