Piggy Experimentalists!
I've just discovered Piggy can officially run on a Pi 2 with Raspbian Stretch!
UPDATE:
Pi Image Now Available For 4 GB + SD Cards
(8 GB + recommended)
Some notes:
Pros:
- the best USB soundcards to use contain a CM108 chipset
- audio buffer at 128 runs smoothly
- did not need to setup xbox drivers
- no pulseaudio problems with this method (provided the alsa.conf file is edited correctly depending on your USB soundcard)
- looks beautiful even on a small screen
- basic MIDI out notation works without any noticeable latency issues (just need to test CC effects)
Cons
- it will take some time and patience to get this going successfully
- still don't know if LGPT works on a Pi 3 with this method
- auto-boot from console and lxsessions has given me problems or just a completely black screen
- and as usual, built-in audio sucks
Give this a shot and let me know if there's anything else discovered or if there's other issues to note!
