Ableton Note
Ableton Note is a playable mobile app for sketching musical ideas anywhere, experimenting with sounds, capturing improvisations, and sampling the environment. Users can start with drum kits, melodic instruments, synth sounds, or their own recordings, then develop ideas by creating beats, melodies, chord progressions, and variations. Note includes a 16-pad percussion grid, a 25-pad melodic grid, piano roll, MIDI editing, quantization, note nudging, velocity changes, transposition, and external MIDI support over USB or Bluetooth. Capture MIDI lets musicians keep something they just played without pressing record first: Note detects the tempo and length and automatically turns the performance into a loop. Users can record sounds through their device microphone into Drum Sampler or Melodic Sampler, then cut, filter, repitch, and process samples with effects.

TyrellN6
TyrellN6 is a compact, sporty synth. Based on concepts and ideas for a hardware synth: a few modules, novel features, analog sound, and low cost. TyrellN6 is the software version manifestation of these ideas. Available as a free download exclusively from the German online magazine Amazona. TyrellN6 is a free virtual analog synthesizer developed by u-he, inspired by the design of classic hardware synths like the Roland Juno 60. It features two oscillators, noise, a ring modulator, and two LFOs with eight waveforms. The audio source mixer includes authentic overdrive and filter feedback, while the twin filter is related to u-he's Diva synthesizer.
