===What you need to know===
Every pattern is stored in the bank/bankXXX/file so if you backup this directory you should be fine.
 
You can write pattern on OpenDingux and push it on your laptop, unfortunately, it could sound little different. The OpenDingux a320 lack FPU so every thing is done in fixed point. On PC and PSP it's done in floating point...
 
You won't be able to push pattern from PC to PSP/Opendingux, it could work but it depend if the Machine is available on the PSP. Today ( picoloop 0.75c ) only Picosynth, Picodrum, DBopl and PBSynth are available on slower platform : PSP, opendingux.
 
The combo Select+UP, Select+Down allow you to raise or decrease the internal volume of the apps
 
If you plug on Windows/Linux a midi cable you can use it with midi sync in or midi sync out. The MMC message ( "play", "stop" ) are received by picoloop, but it doesn't transmit this kind of message. It understand the "stop" and "play" MMC message.
 
You can use midi delay to fine tune the sync between midi hardware and picoloop software.
 
The MDA Drum synth works with file patch ".ds" file. So if you have a laptop with a harddrive which is not an ssd, you should work with a PSU and not the battery to avoid disk spinning down. The automatic disk shutdown will block audio for 10ms and it became really audible. Will be fixed in a latter version.

Picoloop is a synth and a stepsequencer (a clone of the famous nanoloop). The step sequencer play 4 tracks simultaneously, by default each track are 16 steps long, you can set the track to be up to 128 steps. Each track has a synthengine which can be a Virtual Analog, a Drum Synth, a FM synth. Each of the step can be edited on the 4 tracks. So for example, you can set a C4 note on step 0, nothing on step 1 and 2, then a D+5 on step 3 until the step 15.

A pattern of 16 steps is played repeatedly while these notes can be edited in various respects like volume, pitch, filter, lfo etc. All parameters are set step-wise, so you can make huge variation of sound on the same pattern. Each channel's patterns can be saved to file slots and are then available for new combinations. Finally, saved patterns can be arranged in a song structure.

Besides the song editor and manual loading of patterns, there are 3 different ways to modify each channel's patterns so that they form longer structures:

  • 1/2, 1/4 or 1/8 speed
  • Different pattern lengths by track

Picoloop is targeted for linux/SDL compatible system. It uses SDL to render graphics. It uses RtAudio or SDL to render audio out. It uses RtMidi to send and receive midi message, today only clock.

Manual and tutorial for PC/PSP/PSVita/Pocketchip can be fetch here.

Media

User guide

How it works

There is two pane:

  • The 16 steps.
  • the menu which is above the 16 steps.

On the 16 boxes, there is a moving cursor which displays the current played step. And another cursor which displays the current selected step. There is a text menu, which allows you to select channel and edit parameter. All notes in the sequencer can be edited simultaneously.

The menu mode

The menu mode changes the selected textual menu at the bottom of the screen.

This allows you to choose what kind of parameter you want to change, for example, the NOTE, the OSC, the Filter.

In menu mode, when you press left/right, it changes the textual menu in the bottom of the screen.

The edit mode

The edit mode changes the current step on the 16 steps display. In edit mode, when you press left/right, it changes the current step in the sequencer.

menu1

The menu 1 is the first menu. It allows to modify the parameter of the synthengine of the current track. Each synth engine has different kind of parameter. You can:

  • A/R - The enveloppe of the synth.
  • Note - The value of the note trigged.
  • OSC - The oscillator of the synth.
  • VCO - The vco parameter for example a osc1 and osc2 mixer.
  • LFO - The lfo parameter.
  • FLTR - The filter parameter.

Here is the global overview of the most common parameters you will find by synth engine.

A/R:

  • Amp Enveloppe.
    • Attack/Release Amp / FM operator1.
    • Decay/Sustain Amp / FM operator1.
  • Filter Enveloppe.
    • Attack/Release Filter / FM Operator2.
    • Decay/Sustain Filter / FM Operator2.
  • Trig/Amplification.
    • trig time/Volume.
  • Note:
    • Choose note with "C3" "C4" "D2".
    • Choose note with "dot".

OSC:

  • Choose the two OSC shape of the synth, the drumsynth, the FM synth.

VCO:

  • VCO mix in synth mode, OP1mult/OP2mult in FM mode.
  • OP1amp/OP2amp in FM mode.

LFO:

  • depth/speed in psynth and drumsynth mode.
  • pitchbenddepth/pitchbendspeed in psynth mode.

FLTR:

  • Cutoff/Resonance.
  • algo/mode ( lp/bp/hp ).

menu 2

The menu 2 is a more general menu. You can:

  • L/S - Load and save a pattern track or the 4 pattern track.
  • BANK - Change the current bank which allow you to have more pattern.
  • PSH - Shift left or right the pattern of a track and add bunch of 16 step.
  • MAC - Change the current synth engine, synth, drumsynth, dbopl (adlib fm).
  • FX - Apply fx on the current track delay.
  • BPM - Change the BPM and swing of the 4 track and the step diviser of the current track.

L/S menu

The top menu shows the tracks and patterns.

  • Save your current track by selecting an empty slow, then B+down.
  • Save your current pattern (group of 4 tracks) by selecting a column, then A+down.
  • Load a track with A+up (it will replace your current working track).
  • Load a pattern with B+up (il will replace the 4 current working tracks).

You can clone a track by loading it into memory, then saving it to another track.

The menu below (song position) allows you to order your tracks. You can enter it with Start key.

  • Define Loop start position with A+Up.
  • Define Loop end position with A+Down.
  • Change the values with B+Up and B+Down.

PSH menu

  • Increase the track size (16 steps block) with A+Up.
  • Decrease the track size (16 steps block) with A+Down.
  • Increase the track size (1 step) with A+Right.
  • Decrease the track size (1 step) with A+Left.
  • Navigate into the new steps (move the position by -16 or +16) with the Left and Right shoulder (or TAB and BACKSPACE on PC).

What you need to know

Every pattern is stored in the bank/bankXXX/file so if you backup this directory you should be fine.

You can write pattern on OpenDingux and push it on your laptop, unfortunately, it could sound little different. The OpenDingux a320 lack FPU so every thing is done in fixed point. On PC and PSP it's done in floating point...

You won't be able to push pattern from PC to PSP/Opendingux, it could work but it depend if the Machine is available on the PSP. Today ( picoloop 0.75c ) only Picosynth, Picodrum, DBopl and PBSynth are available on slower platform : PSP, opendingux.

The combo Select+UP, Select+Down allow you to raise or decrease the internal volume of the apps

If you plug on Windows/Linux a midi cable you can use it with midi sync in or midi sync out. The MMC message ( "play", "stop" ) are received by picoloop, but it doesn't transmit this kind of message. It understand the "stop" and "play" MMC message.

You can use midi delay to fine tune the sync between midi hardware and picoloop software.

The MDA Drum synth works with file patch ".ds" file. So if you have a laptop with a harddrive which is not an ssd, you should work with a PSU and not the battery to avoid disk spinning down. The automatic disk shutdown will block audio for 10ms and it became really audible. Will be fixed in a latter version.
