There is another project which closes the distance to the target line:
I started this more than a year ago and after programming this on a PIC development board while at the same time I was asking what people want out of such a project here http://www.madbeanpedals.com/forum/index.php?topic=12399.0
So, after a lot of failed programming efforts, I mananged to output a nice drum sample via the PIC. This made me think about how to implement all the features requested.
The various requirements specified by the community were:
- up to 350 bpm
- Ability to control the level of each instrument via a separate control
- big display
- save and retrieve settings
- ability to mix in the guitar signal and an external source
I took it to the next level and created a new PCB to test aout if it can be done:
and it works nicely so far.
Currently working on getting a display connected.
