AVR Synth part 5 (final)

The connections are simple now.





It got a little wiry but it plays alright.. The following sample is a single note (until the end where I start to improvise :)
The loop is made by the envelope only (decay time)

The original site of JAREK ZIEMBICKI is here
There is this other guy named krüe who modified a little the hardware (used an atmega 32 instead of atmega16 and a 16MHz osc instead of 8MHz) and added a lots of features. Source code included! here

A note. I found that the code on Jarek's site didn't work with my atmega16 so I got the hex file off here where they also sell ready made boards.

My sample is here

AVR Synth Part 2

This is the Digital to analog converter. It uses lots of 1% resistors. The schematic mentioned that for the most significant parts, 0.1% resistors should be used but I didn't use such. It really has no effect on sound (at least for me that I didn't expect anything special).

Again, a little attention to the schematic, can save you from a lot of bugs later...
