Thanks for all of the new synths! Regarding RichFM, can you provide some details on the .txt patch format?

As you may have seen in the RichFM video, the six FM operators are arranged into two chains like this:

The RichFM preset .txt files set the amplitude, ADSR and frequency for each operator. Each preset follows the same format. Here are the contents of the preset 8-bass.txt:

0.4 0.001 0.810811 0 4.32432 1;
1 0 0.378378 0 0 1;
1 0 0.162162 0 0 2;
0.8 0 1.2973 0 0 1;
1 0 0.162162 0 0 2;
0.4 0 1.2973 0 0 4;
2;

The first six lines correspond to the six operators in numerical order. So just be aware that the signal flow of the first FM chain begins with operator ‘3’ but the first line of the preset .txt files represents operator ‘1’!

There are six settings for each line/operator. The settings are separated by a ‘space.’ Every setting can have a decimal (aka ‘1.01’ or ‘0.835’). The settings are in this order:

  1. Amplitude of the operator - A ‘1’ or higher may clip, but it could sound cool.
  2. Attack time - in seconds
  3. Decay time - in seconds
  4. Sustain time - in seconds
  5. Release time - in seconds
  6. Frequency of the operator - relative to the key you are pressing. A ‘1’ is the frequency of key. A ‘2’ is twice the frequency of the key…

The seventh line sets the amplitude of the signal feeding back from the fourth operator into the sixth operator. ‘0’ is no feedback.


The ChordGenerator’s chord-list.txt can also be customized. Here are the default chords - one per line:

maj 4 7;
min 3 7;
sus_4th 5 7;
aug_5th 4 8;
maj_7th 4 7 11;
dom_7th 4 7 10;
min_7th 3 7 10;
min_7th_b5 3 6 10;
dim_7th 3 6 9;
maj_3rd 4;
min_3rd 3;
power 7;
octave 12 24;
sub -24 -12;

The format is: chord name and additional notes to play relative to the root note.

So for the major chord (first line) the mode will play the root note (the one you are pressing with your finger or incoming MIDI) plus two notes: one 4 notes above root, and the other 7 notes above root. You can specify notes below the root note with a ‘-’ before the number (as shown in the sub chord (last line)).

You can use a decimal place with the additional notes as well. For example, if you wanted a de-tuned chord:

maj 4.001 6.99

Thanks for going to the trouble of crafting such a thorough reply!
It may be good idea to add this info (RichFM) to patchstorage, and/or a rtf readme file.

Thanks. I think it is best to just have it on the forum so it can be easily updated if needed.

Segmenti for 201! It plays a sample that gets chopped up into 12 equal segments. These segments repeat with each octave, but the playback speed will change according to octave.

The knobs control the following:
Knob 1: Release Time
Knob 2: Sample Speed
Knob 3 : Sample Select. Select from 10 samples!

It’s super fun to add your own samples! Make sure they are recorded at 48KHz/16-bit.

@chrisk when I add (48khz 16bit) samples to Segmenti, it seems like the root note when playing the patch isn’t C, even though the wav files in the folder start with Cs. Is this intended or did I mess something up?

Total noob here, but I dug around the files and found a box in sampler-voice.pd that said 44.1, which I changed to 48 and now I think the patch is tuned correctly. Please let me know if I did the right thing or if my 201 is going to explode tomorrow?

Topaz 1 + Compac 2 is a synth mode for the 201 Pocket Piano. It features voices from two vintage synths: the Topaz 1 bayan from Formanta and the Compac 2 from Univox.

The knobs control the following:

  • Knob 1: Envelope. The knob is split in half: left side is without attack, right side is with attack.
  • Knob 2: Synth Voice. Select from 12 knob positions. Select 6 tones without vibrato (left side), and the same 6 tones with vibrato.
  • Knob 3: Playback Speed. Sets overall speed - used in tandem with transpose keys.

Polyphony: 7 voices.

Have fun!
