RX7 - FM Synthesizer for NTS1 mkII

This is a simple FM synthesis engine for the NTS1 and Logue platform  that can use DX7 voice patch bank files  . It's emphasize is on  size and portability, instead of accuracy. The patcher tool can be used to create custom units with a single patch, or carts. It also serves as the demonstration tool for the unit.

You can also test this online at   https://music.gbraad.nl/rfxsynths/  by loading the `RX7 FM` synth and importing a voice bank  cartridge.
