Percussive Synth

This bugfix release includes: * Returned the "lost" Perc Synth Sequencer AudioUnit. * Ensured the app's default MIDI in/out works as expected. Some helpful information: Using AUM as an example, this is how you can find Perc Synth AU plugins: Perc Synth Plugin - audio channel -> inserts/effects (middle "+" button) -> Audio Unit Extension. Perc Synth Sequencer Plugin - MIDI channel -> Audio Unit MIDI Processor. If you exchange MIDI within one device, say, in AUM, it's very straightforward, just create a route between your plugins and the Perc Synth standalone. But when you want to send MIDI over to your Mac or another remote device, select "Network Session" as MIDI Input/Output in the app's "midi io" section. On Mac, open MIDI Studio, enable a Network Session and route network MIDI traffic to the IAC Driver device. Using the IAC Driver is helpful because some apps won't provide the "Network session" option. If you encounter any issues with the app or plugins, feel free to reach out to me at vadimrostok@gmail.com
