Here's demos of upcoming versions 2.0 of my MIDI Melodeon and Cyborg GCF apps for iPad, now with CoreMIDI support.

MIDI Melodeon supports both B/C and D/G style layouts, Cyborg GCF supports all three-row GCF-style tunings. Both apps allow transposition +/- one octave in 1/2 step increments.

DSMI really isn't supported anymore so all future versions will be CoreMIDI based.

Both app updates have been submitted to Apple for review and should be available the first week of November.

Here's MIDI Melodeon playing the IK Multimedia SampleTank software synth app running in the background on the same iPad, no external hardware needed!

My restored 1930s vintage Hohner B/C box and the Hohner MIDI Melodeon playing a ThumbJam patch (running in the background on the iPad) I made from individual note samples from the exact same instrument:
