Experimental MIDI sequencer/pattern generator designed for iPhones. // FEATURES - 3 tracks (A, B, C) - Track B runs at half the speed of Track A; Track C runs at half the speed of Track B - Triggers for each track (3 × 8 triggers) - Pitch values shared across tracks (sequence of 8 values) - Heptatonic scales quantizer (5 scale patterns × 7 modes × 12 roots) - Degree mask per track (exclusion of specific degrees from the scale) - Degree offset (transposition) per track - Gate length per track - Track length control for Track A and Track B, with optional reset synced to Track C loop end - Track C Pause control (Track C will wait 0-8 steps before looping back to start) - Swing and BPM clock control - Velocity and MIDI channel (1–3) per track - Velocity can be modulated by LFO (per track) with Rate and Amount control - Optional automatic pattern evolution synced to Track C loop end - Evolution has selectable groups of processes/transformations - Variations generator based on current pattern and evolution settings (16 x 4 variations) - Optional automatic capture of output to .MID files (synchronized to Play button) // EVOLUTION When evolution is triggered, it will randomly select one of the enabled transformation groups and apply one of the transformations contained in that group. Below is the list of available groups and transformations within them: PITCH - The order of pitch values is reversed - Two pitch values are swapped TRIGS - Two trigger states are swapped (within a single track) - Trigger patterns of two tracks are swapped - The trigger pattern of a single track is reversed SHIFT - The degree is shifted randomly on a single track MODE - The mode is changed randomly MASK RND - The degree mask is randomized (across all 3 tracks) FLIP PITCH - The pitch invert state of a single track is changed (the first step value acts as the axis and other values are flipped vertically around it) # of STEPS - The track length of A or B is changed to a random value BPM • BPM is halved or doubled • BPM is inverted (120 BPM taken as the axis) • BPM jumps to a random value MASK SHIFT • The degree mask is shifted horizontally by one step (left or right) READ 1ST • First variation on current variation page is loaded (this transformation is excluded from variation generation – can only be triggered by Track C loop end). // PRESETS There are 5 × 24 available slots for user presets. BPM and scale settings can be ignored when loading a preset. Evolution variations (64) are saved within presets. // SAVING TO MIDI FILES Output can be automatically saved to a .MID type. File will be located at the “On My iPhone/sqsl Mantra” folder and named using the current date and time. Takes start when PLAY is activated and end/save when PLAY is deactivated. File saving can be enabled (“AUTO SAVE” setting on the MIDI page) even after playback has started, since note events are always automatically captured in memory. Important notes: - Mantra does not make any sounds on its own, it generates MIDI messages (notes). - Mantra is standalone application and it can not be loaded as AUv3 in other apps/hosts.
