nanoloop FM manual
new in version 0.2update here
- bugs fixed that caused crashes
- new sound types: high pass and half sine FM
- improved pulse width effect
- stronger click (r)
- second voice added to L channel
- illuminated sequencer grid
- slowly increasing range for randomization
- pingpong / random playback modes
The square wave sound is generated with a new modulation scheme that has a slightly different "filter" characteristic: While the wave formerly had a more triangular shape, it's now a fully symmectric square which appears louder with increasing modulation / "cutoff". The pulse width effect works much better this way.
New / changed functions are marked red
The LED display is divided in 3 areas:
The orange rows on top show data values: bars, icons, numbers
Red dots in the middle represent the structure to edit. It is navigated with a green cursor.
On the bottom there is the green menu for parameter / channel selection and transpose functions.
There are two different views:
- In patterm view, you edit the currently playing pattern.
- In file fiew, you save and load patterns and arrange a song.
In pattern view, there are 3 different modes:
Sequencer, parameter menu and global menu.
enters paremeter menu. In the menu,
toggles between parameter menu and global menu,
returns to the sequencer.
There are no "instruments", all parameters are per-step. In menu mode, all steps are edited at once and the values of the pattern are displayed in the data area.

Editing functions are the same as in sequencer but applied to the entire pattern.

In r channel, chords are played as arpeggio. Intervals can be up to one octave (12). When set to 13, sound is muted and arpeggio is stopped, thus functioning as a short gate.
In L channel, the second voice plays at the first interval in semitones plus the second interval in 1/16 semitones. For detune/phasing effects, set the first interval to 0 and the second to 1 or 2.
In the r
adjusts the initial click (for drum sounds), on the other channels, there is a long low-level release for a simple reverb-like effect.
|    ||"filtered" square wave with low / high pass
|    ||normal FM with sine / half sine
Technically, the square is generated by sine wave modulation, too and FM amount controls the "filter cutoff". FM frequency corresponds to pulse width.
Meta step allows to play a step only every 2nd or every 4th time. It's a simple but powerful way to extend the pattern beyond the 16-step grid.
