DETUNE Ltd. has answered my prayers! I've been asking for a serious Frequency Modulation (FM) synthesis workstation on the iPad for a year now. Today they have delivered with an emulation of the classic Yamaha YM2151 chip. This chip was used in 80s Arcade games, and is the bigger brother to the classic YM2612 used in Sega's Genesis/Mega Drive.

This workstation features 8 synth parts, each with their own 4 Oscillators of FM goodness. That's a lot of synthesis! When you add it all up that even beats the iMS-20 for total Oscillators. There's a built in sequencer for working with all of it, as well as an "Easy Mode" for people not familiar with the Dark Arts of FM.
