OFFLOOP Quickstart

Now scroll back up to the top and look at the Playback box top left. These settings affect all 4 channels by default. The A’s are all highlighted in green so if you try and move the fader it won’t work. Disable the automation for that parameter by clicking the A and now the fader will work.
The faders are :
Cont Note (or Transpose)
Global Root note
Global Scale
Tempo

Pressing the A’s here will record automation into the sequencer rows below enabling complex key layouts that can then be tidied up manually.

To the right of the fader rows are 2 columns of buttons, these are for quick editing of the faders. S-1 and S+1 modify only the selected loop area, the other buttons affect all 32 steps.

Scales:
CR – Chromatic
M – Major
m – Minor
PM – Pentatonic Major
Pm – Pentatonic Minor
B – Blues
G – Raga G
Hm – Harmonic Minor
Mm – Melodic Minor
S-M (Selected Loop) to Major
S-m (Selected Loop) to Minor

Next go back down to the channels and randomise channel 2, now you have 2 channels playing together in key. Can you see the Delay A and Delay B panels? The delays are not working because the inputs are on zero. Increase the input to 100 and bring the feedback up to about 60. The delay can now be heard. Try changing the time to 1/8 or 1/4. Nice. The filter on the right limits notes higher or lower from being played by the delay by changing them to these notes, this is especially useful when you start pitch shifting the delays, the feedback can get quite out of hand. Remember these delays are on the midi notes, not the audio.

Going back to the top now there’s a LINK BPM / Freq on/off button in the Frequency Box. This links the pitch of the sequencer to the tempo which sounds like playing a sample up and down a keyboard and can be heard by changing the tempo using the fader. Groove & Timing:
Shuffle is shuffle, + and – on a slider.
Noise/Jitter brings in timing inaccuracies.
Frequency Multiplier is a global octave up/down setting.
Clock Mult divides or multiplies the clocks for Channel 1-4 (and can be recorded and automated)
Loop Controls : Loop Length is the length of the control automation loop, Automation Clock Mult is the speed of the automation loop, remember this won’t affect the speed of Channels 1-4, but does control how long each fader lasts in the automation. The Loop Offset fader for the Control is great for writing different sections of the song, using the S-1 and S+1 buttons to sculpt and you can loop different sections of the control.
Next box is Quantization & Resolution. 24, 48, 96 notes per pulse/quarter, this emulates the gritty timing characteristics of early sequencers with an added snap mode for how the quantisation is done. This is subtle but interesting, especially when you get a lot going with the sequencers.
Last box is Output. Set Midi Port. When you first run the sequencer it will ask permission to access the Midi ports, just click yes. Delays also send out Midi on assignable channels. I’ve not fully tested the Midi yet. OffLoop is still very rough around the edges but it is only a couple of months old and I’m amazed it works at all and in a browser too. Enjoy!!

The latest version of OFFLOOP is here

BTW there are 3 preset boxes to save presets. The top one is the main Settings one. When you save a preset here it will also save an Automation preset and a Channel Note preset with the same name, just a different prefix. Once you have some presets saved you can mix and match them which is great for trying out different chord structures.

Previous version and presets

If you have saved presets in previous versions these will be lost with the new version. However – by opening the previous version and exporting all the presets (top preset manager is global) you should then be able to import them into the new version. The old version will be exported to your downloads folder and you can import that. Let me know if there is an error.
