Transfer

Max for Live device meant for making it easier to run timbre transfer in Ableton Live using real-time neural network models.

Requirements

• nn~ v.1.5.6 external: https://github.com/acids-ircam/nn_tilde/releases/tag/v1.5.6

Note: most recent nn~ v.1.6.0 release is not supported!

Quick start

• Download/clone this repo. For transfer.amxd to appear in Max for Live/Max Audio Effects in Ableton, on MacOS you can run:

git clone https://github.com/wwerkk/transfer-m4l.git ~/Music/Ableton/User\ Library/Presets/Audio\ Effects/Max\ Audio\ Effect/transfer

• Add the repo directory to the Max Path via Options/File Preferences.
• Download the nn~ Max MSP release appropriate for your system and put it somewhere in your Max path, ie. this repository.
• Drop the M4L device as an audio effect on any channel you like.
• Hit the Download button to download some of the pre-trained RAVE models made available by kind people of IRCAM.
• The menu on top of the patch should automatically populate with available models.

Use

• Pick the model you want to use.
• Turn up the Wet gain (it's all the way down by default for safety reasons!).
• ???
• Profit.

Hints

• Values in each latent dimension can be scaled, offset and modulated with noise using the multisliders.
• The menu below offset controls wavefolding settings in case your latent values go out of set range.
• Latency is unavoidable, but can be reduced by changing the Buffer size setting to 0. This is pretty CPU heavy, so you might have to trade-off by increasing the global buffer size in Ableton Preferences.

Adding your own models

You can add your own models by dropping them into the nn_models subdirectory, or replacing it with a symlink to a directory of your choice containing the models. Hit Refresh to repopulate the umenu.

Saving state

The current model and slider state should correctly save with the Live Set and device presets.

Warning: due to how Max and Ableton interact, opening up the patcher (Edit in Max) seems to initialise a new copy with the default state, meaning any edits will also need to be saved as a separate .amxd file.

Note

This is a work in progress, so feel free to open up issues for any bugs encountered or features you'd like to see. Feedback from Windows users is especially appreciated, since I don't have any means of testing on that platform.

Demo

A proper one is due at some point. A less proper video of simple jamming can be found on my YouTube.
