How do I create a keyboard shortcut that act as Is Touching ?

Hello !

I made a kind of online drumbox where you can play with some techno loops.

A button allow to make the kick roll (with two differents speeds).

Everything goes fine when I use the touch control "Is touching", but when I try to create a shorcut with keyboard controls "Key is down/On release" it soudn very "clicky" with lots of artefacts.

My guess is that it alterns very quickly between -150 and 0 db, but I can't figure why.

You can test it there : https://boomboomfactory.org

To see the issue more accurately, after selecting a track and click on play, you can click on the green KICK button while holding SHIFT.

If you click on blue button "kick roll x2/x4" it should sound ok (almost no clic while holding the clic).

If you click on the Q/A or W/Z(qwerty/azerty) you should ear a lot of "audio clics" while holding the key.

Does anybody know what I should do to have a shortcut that have the same behaviour ?

It is possible to simulate "Is touching" with keyboard ?

Here are my event/action if it can help :)

(only difference is that for keyboard shortcut I doubled the event because there are two differents key, you only see one at the bottom the otherone similar except for the audio tag)

Thanks !
