sqsl Puzzle is a conceptual MIDI sequencer and controller for iPad. Interface is composed of central zone and switching controls placed around the edges. Central zone can display playable pads, sequencer, read/write positions (presets saving) and various setup parameters.
Pads:
There are 12 pads with assignable program, pitch, velocity and density (probability) - when pad is touched, note message is sent out preceded by program change message (it will change preset on target devices that support it - eg. hardware mono-synths with presets). Alternatively, MIDI channels or CC value can be assigned instead of programme changes, in that case pads will be sending notes on different MIDI channels or send new CC value.
Pad parameters (program, pitch, velocity, density) can by adjusted manually by sliding vertically on the pad area or can be assigned randomly by tapping on pad when RANDOM is active. Range from which random values are selected can be limited in setup.
There are 8 switchable “pad pages”, each containing assignments for 12 pads - pad pages are selected using coloured buttons around the top edge. Parameter(s) of all 12 pads on the page can be randomised (within range specified in setup) by tapping on already active pad page button.
Sequencer:
Pads can be sequenced by single-track (monophonic) internal sequencer inspired by wave interference rhythm theory of Joseph Schillinger. Sequencer is running through 16 positions. Pads are assigned to positions 1-12 by default, positions 13-16 result in silence/no notes send out. This pad-position assignment can be changed using offset parameter found on sequencer page.
Sequence (order in which 16 positions are accessed) is based on 4 counters (A, B, C, D) running from 15 or less to zero. Each counter has its “resulting value”, which can be 0 or 1, 2, 4, 8 (respectively for A, B, C, D) and sum of all counters resulting values defines current sequence position (pad). When counter’s count is not zero, it’s resulting value is zero. When count is 0, resulting value is 1 for A, 2 for B, 4 for C and 8 for D counter.
Sequencer/counters length setting is accessed by tapping on SEQUENCE button. There are 6 columns of 4 buttons. First column defines offset of pads/sequencer position assignment. Coloured 4 columns in center define counters lengths. Last column defines loop length of current sequence - number of steps after which all the counters are reset (each button counting for 16 steps). If no loop length is set, counters will not reset and the sequence will repeat naturally.
Offset and counter lengths buttons are defined by state of 4 buttons: upper buttons counts for 1, second for 2, third for 4 and last for 8. Sum of active buttons gives the actual parameter value.
Similar to pad pages, there are 8 sequencer pages (coloured buttons around the bottom edge) that can be used to momentarily store sequences and switch through them. Tapping on already active page when RANDOM is active, results in randomisation of counters lengths (new sequence).
A/B Layer:
There are 2 layers (orange and teal color) each with separate pads and sequencer slot settings. Layer B can be synchronised to follow BPM of layer A or run independently.
Setup:
General parameters (per layer): MIDI Output, MIDI channel, BPM, swing, clock division, clock density (probability of clock pulse being randomly ignored). Randomisation parameters: preset, semitone/octave, velocity and density range.
Read/Write:
There are 8 pages each with 56 positions where current slots and settings of all pads and sequencer slots can be saved. Read/write action can be used without stopping playback and read operation can be set in setup to affect only to single (current) layer.

Limitations
Standalone app (no AUv3), does not produce any sound on its own and is not recommended for iPad Mini (controls become too small).

Excited to try this! Will be tucking in later today for sure
Cool! I still haven’t gotten any of their apps yet but they all look right up my alley. One day 😂
Bit the bullet (tho it's near the top end of my app budget) and making some interesting patterns - seems a little more understandable than Michal's other 2 apps though I guess if you've played with those you've got a bit of a feel for how his brain works...!
I think I need some kind of decision matrix. All three apps are ‘conceptual’. What does that mean? What are the commonalities, what are the differences between the three?
Haven't tried the new one yet. Latch is basically mostly for drones, pads etc.... You can record midi loops in it. It also has sliders that can be used to send cc messages, These are automatable. Annoyingly, it doesn't have any preset saving system.
Temp has a preset saving system - albeit you can't actually name the presets. You enter notes and triggers. Notes will be played at random from the notes you enter, you can also specify octave ranges. You can also specify a range of gates and again the sequencer will choose from among these at random. Very nice for constantly evolving melodies.
I guess the conceptual aspect is the mix of user control and randomness.
The description for this new one is baffling! I'm pretty sure it will be just as interesting as the other two, once you understand it. With all these apps you need to read through the online app manual and study the photos, trying things out systematically. It only takes maybe an hour max to grasp them. The interfaces are very beautiful and the experience of using the apps is really enjoyable.
This is another Strokes - initially totally incomprehensible but once you start understanding some of the basics it can create something pretty amazing.
Thanks.
It certainly has me foxed. What's amazing is that he has others yet to come, according to what he's saying on his site and social media. It looks like I need to go to sqsl university! I believe once I can crack the code to using these, some magic might come of it. I agree with you about the beauty. They're like science packaged in art. Like the perfect piano.
I was a bit confused by this new one at first but then it clicked. Pretty cool! Definitely, if you manage to crack one of these apps, the others are much easier to grasp.
