sqsl Temp vs In Theory - Interval Keyboard Usage & Stats
sqsl Temp is a conceptual ambient MIDI sequencer for iPad. It has 3 independent layers (ABC). Each layer consists of 10 slots divided into 2 groups. Slots contain settings and parameters of 5 tracks. Tracks can be 16 steps long and triggers can be placed on steps, resulting in monophonic MIDI note message or alternative event (see below).
- Layer paramaters: transport (play/pause), MIDI output, clock speed, semitone and octave shift (transposition) per track, Alt mode, Hold mode, global lock/per track locks, global mute/per track mute, octave transposition.
- Single-value track parameters: track length, track start, clock skipping probability, lock loop length, random jump probability, random step probability, clock division, step map.
- Multiple-value track parameters: semitone and octave, velocity, gate length, MIDI channel (1-8), MIDI channel offset (+8), Alt event, note delay.
When parameter has multiple values selected (multiple-value track parameter), algorithm will randomly pick one of the values each time playhead encounters a trigger. If Lock is activated, the parameters are preserved and are not re-generated on new track pass. Lock loop can be from 16 steps up to 128 steps long.
Parameters can be adjusted for: current slot, group of slots (5S button), current slot on all layers (3L button), group of slots on all layers (5S and 3L button). Currently playing slot can be locked for playback (long press) so other slots can be edited while locked-one is playing.
"Alt events" can be placed on steps instead of note triggers. Alternative events include: flip Hold mode, turn of Hold mode, advance slot in the group, advance slot in the group in reverse direction, go to first slot, go to random slot in the group, change slot group. When HOLD mode is active, note-off messages are not sent - currently playing or future notes are held (tracks are monophonic). When Mute mode is active, track’s MIDI output is muted.
Important notes:
- Temp does not make any sounds on its own, it generates MIDI messages (notes and clock).
- Temp does not synchronise to incoming external MIDI clock but is able to generate MIDI clock signal (clock/start/continue/stop) so other devices and application can be synced to temp.
- Temp was designed for full-size iPads and is not recommended for iPad Mini users (controls become physically to small to use).

In Theory is an interval based MIDI keyboard app with more than 110 scales. It has a keypad at the bottom with the interval buttons like +2, +1, 0, -1, -2 which would change the current note. Zero means the current note, +1 means the note after the current note, +2 means two notes after the current note, -2 means two notes before the current note in the scale and so on.
Above the keypad, you can toggle additional intervals in the scale for creating chord voices. You can also select the notes from an octave above and an octave below for creating rich, extended chords.
You can use your MIDI keyboard to play In Theory as well. The middle C4 key on your MIDI keyboard triggers the 0 (zero) button on the app's keypad. The white notes after the C4 note would trigger the positive buttons, the white notes before the C4 note would trigger the negative notes on the keypad.
You can also toggle the chord intervals with MIDI CC messages. You can set a MIDI CC number and a MIDI Channel for toggling the chord intervals from the settings menu. If you send a MIDI CC value between 0-62, you can toggle the chord intervals respectively.
With the MIDI capabilities, you can also sequence the app with a MIDI sequencer app like PolyBud, ShiftBud, MelodyBud etc.
In Theory has more than 110 scales built-in. You can also use the custom scales you made in ScaleBud 2 app as well. The key and scale could be changed externally from a MIDI controller in AUv3 plugin with the AU parameters.
The circular display on the UI will show you where you are in the scale. Also, when you play a note, you will see the every playing note on the screen with the root note and the chord intervals.
Please note that In Theory is a MIDI app and does not produce any kind of sound on its own. You need to connect the MIDI output of the app to an audio app's MIDI input. For the AUv3 plugin you'll need an AUv3 host app such as AUM, Cubase, Nanostudio, apeMatrix etc.
