A Revamped Mellotron for the 201!

Here’s how to use it:

Envelope knob: Left of noon is fast attack, right of noon is slow attack. Noon is long release, sides are short release.

Tone knob: Select from 5 banks of sounds: Flute, Violin, Cello, Accordion, and Randomizer. All changes to this knob are quantized to the 201’s master tempo.

Surprise knob: Speed (0x – 2x)

The samples used in this patch were obtained for free at http://www.leisureland.us/mellotron.htm
Within Yellotron, each bank of samples is located in its own numbered subfolder. The individual samples are named according to their note (A#3, B3, C4, etc.). Users are encouraged to swap out these .wav files for other mellotron sample sets found at the aforementioned website as they see fit.

This patch is based heavily on spectral_julian’s ORACtron orac patch,
https://patchstorage.com/oractron/

which is in turn based upon callmesam’s Mellowtron organelle patch,
https://patchstorage.com/mellowtron-rework/

which is in turn based upon Pierre Massat’s Yellotron pd patch,

Yellotron : a mellotron with Pure Data

It also uses elements of Topaz1 + Compaq2 by Critter and Guitari.

This is a RAM-intensive patch (!) so anticipate increased boot-up time and less space for presets/saved sequences/samples. A lighter version of Yellotron which only loads one bank of samples and replaces the bank selector with a warble effect is also included. To use this version, delete the file named “module.pd”. Then duplicate the file named “module-single bank.pd” and rename the copy “module.pd”. The 201 will now load the less intensive version. To switch back, repeat the process with the file named “module-multi bank.pd”.

CHANGELOG

1.1: bank changes now only trigger if selecting a different bank, was previously causing crashes at high tempo settings. Also tweaked sampler behavior to avoid clicking when triggering many notes with long decay quickly.

1.0: stable release
