Max For Live #

The KeySwitch & Expression Map is a Max For Live device.

Max For Live is part of the Ableton Live Suite. If you use Ableton Live Standard you have to buy an add-on license to use this device. Ableton Live Lite and Intro do not support Max For Live!

Ableton Version #

The device was originally created in Ableton 10 with Max For Live 8.1.7

I tested it in Ableton 11 and it is 100% compatible.

Generally, it works also in Ableton 9 and Max For Live 7, but there are some bugs or functions missing you should be aware of:

  • Ableton Live 9 uses another font than 10 and 11 which causes some minor issues in the design.
  • You cannot reset a value with a double-click on a live.numbox.
  • If you want to define a MIDI note for the key switch, there is a bug with sharp notes. They are displayed and you can set them with the mouse, but it is not possible to type a “#” with the computer keyboard.
  • Since Ableton Live 9 does not yet have the ability to chase MIDI notes, the key switch settings are only applied after the timeline cursor has passed the envelope’s breakpoint. So you cannot jump through the timeline and the good articulation, instrument or MIDI effect is played directly.

Hardware #

The device has no effect on your computer’s CPU. Therefore, you can use it on any system and there are no hardware requirements.

However, if you intend to use the KeySwitch & Expression Map to work with many tracks and a lot of articulations for each VST instrument in your projects, I would recommend that you have at least 16 GB of RAM. Especially older VST players often preload a lot of a sample into the memory because there were no fast SSDs (Solid State Drives) in their days. This can quickly sum up to several gigabytes.

The device itself also requires about 65 MB for each instance due to the high number of parameter boxes in the KeySwitch Editor, so that you can comfortably create your key switches and easily change them at any time.

How did I measured that? I loaded the device into 100 tracks. Then I subtracted the approx. 800 MB for Ableton with 100 empty tracks and divided the rest by 100.
