I love Pulse Code! They continue to pump out big updates and entirely new instruments for Rhythm Studio, with no In-App Purchases. Hell, you can buy the whole app for a buck right now because it is also on sale!

Today we get FM-3, a step-sequenced 3 Oscillator Frequency Modulation (FM) Synth.

Nice! It looks like a cross between the OP-1 and a TB-303, but with an FM engine.

My video review is somewhat outdated by all these updates.
