PaklSound is a very simple little sequencer, and really a proof of concept application. Here’s what app store says:
PaklSound1 is a simple, multilayer step sequencer. Have a few free minutes or want to try out a music idea? Make up a tune by touching dots in musical patterns — they are played back as a bar sweeps across the screen. Features: – quickly lay down tunes and rhythms – change the tunes and rhythms in real time – use multiple layers (e.g., melody and drums) – increase/decrease playback speed Future versions will add more sounds, layers and other features.
