Keep in Sync with your apps using Ableton Link or MIDI Send MIDI clock or MIDI note as separate channels. This app was influenced by the Korg Volca/Electribe FM synth sequencers as well as TX81z and Orla DSE9 FM synthesizer SEQUENCER The sequencer has 7 channels containing a sequence dedicated to a tone sound. You can create sequences using step edit or bring up the PIANO ROLL for quick step placement. You can just randomly generate steps - either random choice pitches or SELECT NOTES. or shuffle the sequence PIANO ROLL! its easy to create melodies and bass lines fast! Double click step to cycle though octaves or erase across step with finger motion. Mask keys so you can define keys and swipe across bar with finger motion to lay down steps easily. EFFECTS! Each track has echo, reverb and a low pass filter similar to add some spacial atmosphere or emulate an analogue synthesizer. COOL CREATIVE FEATURES! 2nd and 3rd voice generators with detune and transpose by semitomes for fat chorus effects or chorded notes Auto level ducking switchable input from bass metronome or any track Playback timing of notes on sequences - steps triggered either at 4th or 8th timings - a sequence can play slower and last longer equivalent to 512 steps Added a “mutate tone” option that slowly modifies the sound randomly away from original. Added “randomise tone” that completely creates a random tone from fresh. GLOBAL TRANSPOSE! All channels can be transposed simultaneously on the fly to create great layered melodies, and you can choose which ones are ignored (TR LOCK) for things like sound effects. SONG MODE is like a playlist of programs, where you can chain programs from either the current loaded program or imported saved program file. A scene can have any track muted, global transposed, reset counter at start (D.C.) "Da Capo", override step length and control the BEAT ON metronome mode. You can then arm sampling and record the chained programs and export the audio. Save your Songs and they won't be affected by changes in the original programs. EXPORT! You can easily record a perfect loop of whatever is playing and export via AudioCopy or Audioshare as well as email and IOS Folder Export your tones, sequences or whole programs to another device, friend or saved elsewhere SYNC This is compatible with Ableton Link as well as MIDI so you have options for connecting to external hardware or other apps while keeping in time AUDIO ROUTING Output the main audio to other apps such as Audiobus or AUM to allow those apps to record or process your creations EXTERNAL CONTROL Control Mute of tracks with midi keys, volume of track-channel with MIDI CC 176 for channel 1, , 177 - channel 2 etc .. MIDI note input of one track's sound available while sequencer is playing all tracks - selectable tracks controlled by all midi channels (omni) THIS DOESNT ACCEPT MULTIPLE MIDI PER SEQUENCE.
