We need a General MIDI compliant drum instrument.  It will need some code to 
use different samples for each note, without interpolation.

The hard part is making sure it doesn't force Honeycomb as a requirement.

Right now, you can only edit channel 0 in the instrument editing panels.

Some way to set the beats-per-minute.

Right now, only 4/4 time is allowed.

We're never gonna be able to have realistic drums without sampled sounds.

A triangle and a square.

It would be nice to be able to just play and have it recorded in the score.

What's the point of writing a song if you can't save it?

TEMPORARY SOLUTION: Reverting back to NDK 9d will fix the issue.

armeabi-v7a build is broken with NDK version 10 and higher:

All other builds (mips, x86, arm64-v8a, x86_64, mips64) complete without errors.

Moving your finger around the knob should stay with it, but it doesn't.

The current UI is a mess.
