Velocity Keyboard is a powerful velocity-sensitive MPE compatible MIDI controller. FEATURES - unique velocity sensing algorithm that tracks touch force like no other app - Four interface layouts: Keyboard, String, Scale, and Drum Pad - runs as an Audio Unit or as a standalone app - 8 simultaneous sources of MIDI CC parameter control: touch area, touch force (on devices that support 3D Touch), touch Y-coordinate, velocity to CC and up to four MIDI CC control knobs - smooth MIDI pitch bending between notes in both string and keyboard layouts - highlight custom scales in any key - dedicated MIDI modes for maximum flexibility when controlling non-MPE compatible synthesizers - pitch bend correction algorithm plays more in-tune with more freedom of expression when bending between notes (compared to similar MIDI controller apps) - can output velocity as a MIDI CC or aftertouch message to better support synths that aren't designed with velocity sensing in mind What does this app do differently from our iFretless apps? - It uses much less RAM because it doesn't load any audio samples - It has MIDI aftertouch controls, so changes in touch pressure and location that occur after after the start of a note can control MIDI CC parameters - It supports highlighting notes in custom scales - It has piano keyboard, scale, and drum pad layout options - It has updated velocity sensing and pitch correction algorithms - It has better visibility, making it feel more playable on smaller screens, or with a larger number of rows and columns

The whole Roland S-1 panel on your iPhone or iPad, over USB-C. The S-1 hides half its brain behind the Shift key. This editor puts all of it in front of you: all 54 parameters, laid out like the SH-101 panel — the synth the S-1 rebuilds — so the signal chain reads at a glance. WHAT IT DOES • All 54 control changes, with faders where the SH-101 had them and knobs where it did not. • Follows the hardware: move a knob on the S-1 and the screen follows in real time. • 60 factory presets in six categories. Versions of the patch charts from the original SH-101 manual, the club sounds the 101 became known for, and a bank built by ear against the unit. • Four sequencers: step piano roll, three-layer euclidean, scale-based generative and arpeggio. • Motion recording: move any control while it plays and it gets automated step by step. • A randomizer that blows up the whole engine and still leaves something audible. • Your own sound library, with export and import. • Light and dark. Spanish, English and Portuguese. WORTH KNOWING You need a Roland S-1 connected over USB-C. The editor makes no sound of its own: it sends MIDI to the unit, and the unit is what you hear. The S-1 does not answer SysEx. There is no way to read a sound out of it or store one over MIDI, so the library lives in the app and WRITE is pressed on the unit. The app selects the target pattern and dumps the sound so all you do is confirm. The whole parameter map comes from the official v1.02 manual. PRIVACY Nothing is collected. No accounts, no network, no analytics. Your sounds stay on your device. Made by fantasmogenesis.

Verdict
The clearest difference is price: S at $2.99 against Velocity Keyboard's $9.99. Velocity Keyboard's advantage is iOS requirement (11.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
