Trigger sample from Cajon Hit?

SparkleBear

Hey yall,

I tried a few methods including A2M and guitarmidi2 to convert my cajon hits into midi to trigger a drum sample. Does anyone have any idea about this?

Basically when I hit the low note of my cajon i want to make a kick drum bloom beneath it. I couldn't get guitarmidi or a2m to track that properly.

Any advice welcome here.

Thanks

Something like FAC Envolver with a filter before it to cut the transients of higher pitched hits. Basically you need to adjust the filter until, as much as possible, all you hear is the low note. A peak EQ with a narrow Q centered around the fundamental frequency should work. Once that's done, set up Envolver to fire off a note on the transient of the filtered hit.

It won't be foolproof, and it may add too much latency. But it might work.

@FredAntonCorvest Please make a built for purpose app based on this idea for drummers!

I experimented in 2019 with FAC Envolver and the iPad Mic for input and found I needed a StreamByter script the detected the moment of the peak for each transient to get really good timing. I fed the midi into a drum app snare drum and was able to play on a drum pad.

Instructions from the original thread can be found here:

Envolver settings:
Env->MIDI = CC Off (on BOTH FAC Envolver's 1 and 2 circuits)
Gate->MIDI = CC Off (on BOTH FAC Envolver's 1 and 2 circuits)
Gate->Midi = (Transpose = -24) A# and OFF on #2 unless you want to trigger 2 Notes use the unlink to have 2 distinct thresholds.
Tweak the Threshold Knob to capture only the taps as MIDI events.

I think this is the Streambyter (a free app) script based on its title in my Streambyter app.
