Tempo (%) management in MiDi

Hello everyone :)

I have been discovering M4L for a few days and my poor English absolutely does not help me advance in my search.

Until then, for a few years I worked my bass on Guitar Pro and Ableton which had the role of an instrument. Guitar Pro has a very useful asset for work, which is not found elsewhere, it is the management of the % tempo, per range of +/-5%.

To summarize: when reading the score, we select the tempo and the "-" & "+" keys on the keyboard allow you to increase or decrease the tempo in a range of 5%. There is also a drop-down menu with a certain number of % to choose from and there is also the solution to fill in the tempo we want this time in bpm.

The disadvantage is that all this is not controllable in MiDi...

The idea would therefore be to export the pieces, exercises etc... from GP to Ableton in MiDi and use M4L to build a work tool that would respond to this:

• Show in the same pop-up:

  • A - the original tempo (I found that)

  • B - the value in % of the new tempo (100% if = at the original tempo)

  • C - the tempo obtained (A x B = C)

• Assign a MiDi controller (in my case MC8, why not equipped with Lehle Dual Expression S) that can:

  • +5% of A

  • -5% of A

  • Return to the original tempo A

Hoping to have aroused the curiosity of enthusiasts ready to help me in my adventure! I'm not looking for a turnkey tool but maybe ways so that I can build all this myself :)

Thank you in advance!

Sincerely,

Dje
