I am programing a drum machine in Arduino with sequencer and everything and I am doing pretty well
I wanted to add some effects for it, and thought of a BASS BOOSTER so the bass drum could sound very fat and also a little distorted if the user wanted it (you can turn up the bass booster and lower the bass drum volume if it gets too loud).
I breadborded a circuit I found online:
And it almost has the sound I am looking for, so it’s fine for starters. As you turn P1 and P2 it goes from NO SOUND to a PUNCHY BASS SOUND.
Now, I want the user to be able to go from a DRY sound (not filtered) to a BASSIER sound (filtered and distorted) and this booster circuit only outputs the filtered sound.
It’s not really what I wanted but I thought of using an op-amp as a mixer for the dry and wet output, the dry beeing always on and you can add bass by mixing the output as you turn a knob.
I then breadboarded this circuit:
and connected the dry output to one of the inputs and the wet output to another, but I am not getting both sounds at the same time, as you turn the P1 and P2 from the boost circuit it makes something strange: At one end you get full dry sound and at the other end you get the full wet sound, the weird thing is that at the middle point you get a VERY THIN sound, with no bass.
I also looked at “blender” circuits, but didn’t tried yet.
What do you think???
Thanks a lot!
PD: attached an mp3 sample so you can hear it, it’s a little quiet (doesn’t has the bass boost!)
