in a post else where somebody asked: I have several Inputs and I want to use them as side-chain input to a merge. I want to control which of the inputs is used by a multi-parameter. Only one input should be used at any time.
In this tutorial I show one possible setup. It's just for the sake of demonstrating things. Exactly the same result could be achived with another trick, but that's another tutorial.
This tutorial has 4 parts:
- Basic Setup (patch included)
- Setup of the multiparameter
- Configuring the banks (patch included)
- Final result and ideas for experiments
- It's one main Oscillator
- 4 oscillators "Osc 1-4" which are the side-chain inputs for the merger. For the sake of the demo I chose basic Osc and just setup some different values that you can hear the effect
- A mixer where Osc 1 -4 are connected as inputs. Exactly this mixer is at the heart of this tutorial. It allows me to control the volumes of Osc 1 - 4 which is passed on to...
- The Merger where #1 is the main input and the mixer output #2 is fed as side-chain

The goal is to use only 1 of Osc 1 -4 as input at any time. We use a multiparameter to control this.
But how are we gonna solve this "mutual exclusive" thing?
We can translate this into settings of the volume controls of the mixer.
If for instance you want to set Osc 1, then: Vol 1 in the Mixer is +12db, all others are set to "silence"
If for instance you want to set Osc 3, then: Vol 3 in the Mixer is +12db, all others are set to "silence"
and so on.
So this means we need "4 configurations", each controlls more than one parameter.
This is an indicator for banks mode!
So let's go through it
- Go to M1, set it in banks mode (Picture 2, #1).
- Click "learn" (Picture 2, #2)
- Move each of the 4 volume controls in the mixer...which will add four parameters to each bank (Picture 2, #3)
- Don't forget to give M1 a name, not depicted
- Set the "Value mode" to "By bank number" and the "Steps" to 4 (not depicted)
Now we are almost there: Configure the banks
Now it's simple to configure the M1 banks. Each column, for instance 1 represents a "configuration" of all 4 volume controls, so to set up config 1, i.e. Osc 1 on , all others off

Use the above patch and uncheck "edit" mode.
You'll find a single knob which allows you to select the values between "1" - "4".
By switching it to 2, you chose configuration number 2, i.e. Osc 2 serves as input all others are silent.
Fun part for you now is to do some experiments on your own.
For example: Try to add a 5th configuration with all Oscs "on", or with a individual mix of them.
Or you could also control the "merge algorithm" which is used by each of the configurations/banks.

Any questions regarding this?
Any wishes for other tutorials?
