Raph Levien f52201cc11 Add pitch LFO This patch wires up the LFO to the synth unit, and makes it affect pitch (control over amplitude is not there yet). It also adds LFO delay to the base LFO implementation, and there are some other cleanups as well (for example, not unpacking patch data every note). LFO speeds, delays, and pitch modulation ranges have been calibrated against the DX7, but testing hasn't been exhaustive.	12 years ago

Raph Levien f52201cc11 Add pitch LFO

This patch wires up the LFO to the synth unit, and makes it affect pitch
(control over amplitude is not there yet). It also adds LFO delay to the
base LFO implementation, and there are some other cleanups as well (for
example, not unpacking patch data every note).

LFO speeds, delays, and pitch modulation ranges have been calibrated
against the DX7, but testing hasn't been exhaustive.

README for C++ codebase

The C++ codebase will eventually be the primary sound generation module
for this app. It's still experimental, and not yet wired up to the Android
parts, but can be used to make sound. The best way is to use the simple
test app for the Mac.

To build, edit src/SynthApp/SynthMain.mm to change the path to ROM1A.SYX
to the actual path. These patches can be downloaded from:

http://www.abdn.ac.uk/~mth192/dx7/dx7patch.zip

Also change the "KeyRig 49" string to match the actual USB name of your
MIDI controller. Then "open src/SynthApp.xcodeproj", then do "Build and
Run".

The File Open menu command is hooked up as well and will load SYX format
DX7 patch files (32 patches per file). Send program change midi events
with the first 32 program numbers.

The xcodeproj files are checked into the repo, but they are autogenerated
from .gyp files, which are the authoritative masters. To modify the
build, change the .gyp file, then run "gyp" in this dir. For changes
to the core, also change ../../android/jni/Android.mk .
