Mixpult

Catchy night techno from your phone. A loop keeps going round and you play drums, mood, bass, melody and your own voice into it: touch a pad to hear it, hold the button to record. No notes, no chord names, nothing that can sound out of key.

What's in it

• Six tabs. Drums, Mood, Bass, Melody, Voice and FX. Each track is one 2D pad (up/down picks the beat, mood or pitch; left/right blends three sounds from calm to hard) and a hold-to-record button. The loop is drawn as a glowing line.
• Your voice. Record short clips with a count-in and chop them in from a launchpad, through a vocal chain in the Fred again.. spirit. New songs start with "work it" and "do it".
• FX. An XY pad (filter left and right, a big hall going up), a beat-repeat stutter that lands back on the beat, and a breakdown that drops when you let go.
• Share. The share button makes a link. Whoever opens it hears your track, gets a short tour, and remixes their own copy; the link always plays the original.
• First run. A guide to full screen, then ghost thumbs show the moves.
