Sequins

Sequins is a basic, dual-channel sequencer.

The app provides four 16-step sequences per channel and CV-control over various channel parameters, including scale mask, octave, pulsewidth, clock multiplication and division. The four sequences can be chained in various ways, providing sequences from 4 to up to 64 notes. The sequence data is stored along with the other settings (whenever settings are saved).

Description

  • the sequence editor works similarly to the scale editor in the quantizer modes:
    • in the main menu, select which sequence to edit by adjusting the sequence # parameter.
    • then right-click on the item displayed right below (--> edit) to open the sequence-editor.
    • mute/unmute notes by clicking the left encoder: the step value is displayed in a format x+y.yy, where x is the octave (above or below 0.00V) and y.yy gives the semitone offset. for instance +2+2.23 = 2.23 semitones above octave #2 (=~ 2.000V).
    • adjust the sequence length by pointing the cursor to the far right, then turn the right encoder.
    • (simultaneously push down the left encoder to also mute/clear the steps that are being added while expanding the sequence).
    • to adjust the pitch, simply move the cursor to a given slot, then turn the right encoder: this will increase or decrease the pitch in semitones (= step size: 1.00). note these values are pre-quantization, so the effect this has will depend on the chosen scale.
    • to fine-tune the pitch (= step size: ~ 0.01), hold down the left encoder while turning the right encoder.
    • note: the number displayed when adjusting the note values is the actual (pre-quantization) DAC code (that’s far from ideal, i know …). details on what those numbers mean can be found here.
    • in the sequence-editor, you can use the up/down buttons to select which sequence to edit (#1 - #4). (this makes it possible to edit sequences ‘offline’, ie make adjustments to, say, sequence #2 while sequence #1 is playing).
    • copy+paste: in the sequence-editor, long-press the left encoder to copy the selected sequence. select a different sequence slot, then long-press the down button to paste it into that slot. copy+paste works across channels. (note: once copied (or pasted), sequence data will be stored in a temporary buffer for about 15 seconds, after which it’ll expire.)
  • the playmode and direction settings offer various ways of moving through the sequence(s):
    • - (default): advance by trigger, using the chosen sequence and direction settings.
    • SEQ+1 - SEQ+3: ditto, but cycling through 2, 3, or 4 adjacent sequences (= allows up to 64 notes).
    • TR+1 - TR+3: ditto, but jumps to the next sequence only if/when a trigger is received at the aux. trigger inputs.
    • ARP: arpeggiate the sequence.
    • S+H#1 - S+H#4: CV-address, when triggered (sample and hold).
    • CV#1 - CV#4: CV-address, free-running.
  • note: when in CV-address mode, the CV adr. range setting adjusts the resolution of the chosen input (CV1-CV4), relative to the length of the sequence (ie, you’ll either need 5V or 10V to move through the entire span of the sequence).

  • the secondary/aux. clock inputs (TR2, TR4) can be used to either cycle through the sequences (see above), or they can be selected as a reset/mute signal (reset/mute). the options are: RST2, RST4 (reset) and =HI2, =LO2, =HI4, and =LO4 (mute when aux. clock goes high, respectively low.). NB: When using a clock divider or the like (or anything that will introduce latency relative to the main clock inputs TR1/TR3), it can/will make sense to increase the trigger-to-processing latency (see the Trigger delay setting). This will make sure the auxiliary trigger (or control voltage) is processed within the current update window. (Also see Quantermain above for an extended discussion of the trigger delay setting).

Available settings (per-channel)

Setting Meaning

sequence # select sequence #1 - #4
--> edit edit sequence
playmode chain sequences (SEQ+x), advance by trigger (TR+x), or CV-address
direction forward, reverse, pendulum1, pendulum2 (repeat first/last), random, Brownian
-->brown prob (if direction=brwn (Brownian)) probability (p) that sequence direction (up or down will reverse on the next step, 0 means p=0, 255 means p=1)
mult/div set clock multiplier / divider

--> aux +/- (if aux. mode=copy) offset at C/D outputs (in octaves)

--> att shape (if aux. mode=AD, ADR or ADSR) shape of the attack segment of the envelope output on the auxiliary channels (C or D outputs). See the Piqued app for details of envelope segment shapes.
--> dec dur (if aux. mode=AD, ADR or ADSR) duration of the decay segment of the envelope output on the auxiliary channels (C or D outputs)
--> dec shape (if aux. mode=AD, ADR or ADSR) shape of the decay segment of the envelope output on the auxiliary channels (C or D outputs). See the Piqued app for details of envelope segment shapes.
--> sus dur (if aux. mode=ADSR) duration of the sustain segment of the envelope output on the auxiliary channels (C or D outputs)
--> sus level (if aux. mode=ADR or ADSR) level of the sustain segment of the envelope output (for ADSR envelopes), or the level at which the the decay segment transitions into the release segment (for ADR envelopes) on the auxiliary channels (C or D outputs).
--> rel dur (if aux. mode=ADR or ADSR) duration of the release segment of the envelope output on the auxiliary channels (C or D outputs)
--> rel shape (if aux. mode=ADR or ADSR) shape of the release segment of the envelope output on the auxiliary channels (C or D outputs)
--> loops (if aux. mode=AD or ADR or ADSR) sets the number of loops for each envelope output on the auxiliary channels (C or D outputs), defaults to 1 (see also the Tip below)
reset/mute select reset/mute source (mute being more like ‘pause’)
clock src choose channel clock source (TR1 or TR3)
trigger delay trigger-to-processing latency (accessed via CV menu): details see Quantermain above

Note: There is a bug in the v1.3.3 firmware which prevents the gate auxiliary output from working unless the mult/div for that channel is set to x2 or above. This bug was fixed in v1.3.3b firmware.

CV menu

  • enter the CV menu by pushing the down button:
    • use the right encoder to assign CV input channels 1-4 to a channel parameter (currently available parameters are: transposition (in octaves), scale mask, sequence number (1-4), sequence length, direction, multiplier/divisor and pulsewidth. The quantiser/sampling trigger delay (see notes for Trigger delay in Quantermain) and the clock src (clock source) can also be specified in this sub-menu, as well as CV input mappings to these envelope parameters: att dur, dec dur, sus lvl, rel dur and env loops. By using CV to control env loops, a sort of psuedo-ratchetting effect can be obtained. Other envelope behaviours can also be specified (see the Piqued app for details): att rest, att fall gt and dec/rel reset.
    • return to the main menu by either pressing the up or down buttons, or by moving the cursor to an empty field and then pressing the right encoder button.
    • clear all mappings (per channel) by long-pressing the down button (in CV menu)
