The library of devices at maxforlive.com is becoming quite daunting. Considering that most of them are free makes M4L seem like a must have for Ableon users. The sheer number and quality on offer means that there's pretty much something for everyone.
Here's one added a few days ago. The description reads, 'Add APC40 hardware control to the Mono Sequencer to create basslines and melodies in minutes without ever touching a mouse or a MIDI keyboard. Unlike other grid-based step sequencers for the APC, this uses the grid to show you a complete sequence of up to 40 notes while you quickly adjust the pitch, velocity, octave, and duration of each step with the ringed encoders. This gives you much more precision as well as complete variety in note selection.'
It's free and I'll be spending some time seeing how I can integrate it into my workflow.
There are also paid devices like this one.
I've purchased from K-Devices in the past and will probably bite the bullet and grab this one too.
'TED is a Max For Live highly editable LFO that may act also as a function generator. With TED's signal, you can modulate any parameter in Ableton Live: from other devices's parameter, to Live's UI, to any third party plug-in.' All that for 5 euros.
I'm trying to get through evaluating all the available devices, currently 1932, for my Masters specialised project. I'm going to be building Ableton templates using Max devices for improvisation purposes. I've got through a few hundred so far and there are plenty of diamonds in there. Back to it.
