Map a Key of SST49 to Octave Settings of Drumpads

Hi csxdy,

I think what you are asking for is similar to my tip for using the SS25 DRUMS button to switch between BM2's drum and key modes, which is described in this thread.

It might be a little different as we might need to do more complex mapping of the pads rather than just a plain transpose.

I don't have an SS49, but if you could use Midi Monitor or midi wrench to capture what MIDI messages the SS49 pads send, then I maybe able to construct something for you. I really need the MIDI note numbers that the pads send rather than the note names.

Do you want the drum pads to stay on channel 10 or do they need to be mapped to another channel on the way through?

Regards, Nic.

Hi Patrick,

OK, the NoteMapper will affect all channels, so we will need to use the Stream Byter instead for more finer control. This ruleset will move the pad range up by 9 notes to trigger the next set of 9 notes:

# SS49 pad remap
N9 24 = XA 2D
N9 25 = XA 2E
N9 26 = XA 2F
N9 27 = XA 30
N9 28 = XA 31
N9 29 = XA 32
N9 2A = XA 33
N9 2B = XA 34
N9 2C = XA 35
NA = X9

Save the above in a preset and then use the technique in the other thread to switch between the scenes using the DRUMS button. If you get that working, then you can refine further with more scenes and more mapping rulesets and changing the scene triggers with different buttons from the SS49.

I'd suggest you get the basics running first with the DRUMS key toggling between two scenes - one with the above mapping and the other without. Once you have that figured out, then you can get more advanced with more than 2 scenes and mapping the other SS49 buttons to trigger those scenes either in a round-robin fashion or to specifically trigger a certain scene. I can provide guidance on this later.

You may find the midi table useful in adjusting the ruleset above. Essentially you just change the last two digits of each rule to a different note.

Finally, you might notice I remap the channel from 10 to 11 in each mapping and then back to 10 in the final rule. This has two benefits:

1) You don't need to worry about the order of the remap rules
2) If you want to change the channel of the pads only, you can just change the last digit of the last rule (eg. set to 0 to remap to channel 1)

Hope that helps getting you going. Please let us know how you get on and if any more help is needed on setting this up. It might be fiddly at first, but you only need to set this up once!

Regards, Nic.

ok, i am getting close : )

with a push of the Mono Synth 2 Button ( CC83 )
i "activate" Beatmaker 2 and map the Drumpads to the
first 9 Pads in Beatmaker:

# Enter rewrite rules here
# Press 'Install Rules' when done
B0 53 7F = C0 01 +C

N9 24 = XA 00
N9 25 = XA 01
N9 26 = XA 02
N9 27 = XA 03
N9 28 = XA 04
N9 29 = XA 05
N9 2A = XA 06
N9 2B = XA 07
N9 2C = XA 08
NA = X9

when i push the button a second time, midibridge connects the Synthstation to
Thor:

B0 53 7F = C0 00 +C

right now i try to figure out how to have a separate button for the drum transposing, because
when i map it to the "Drum" button, i cannot access it, i have to activate it in the Midibridge scenes.

They all have CC numbers, the Drums button is CC80 so its 50 in hexadecimal.
My problem is that i cannot use the button independent to the other button,
because i have to activate a scene ( drum transposing) without to affect to
loose the ability to switch between scene one ( synthstation) and scene two
(thor).

Wenn Sie auf Deutsch werden schreiben ist das OK.

I think I understand the problem.

You want to use CC83 to switch between thor and beatmaker.
You want to use CC80 to remap the pads when CC83 is pointing to beatmaker only

I think you need 3 scenes:

   scene 0 - thor
   scene 1 - beatmaker, no remap
   scene 2 - beatmaker, with remap

In scene 0 (connected to thor):

# CC83 = scene 1
B0 53 7F = C0 01 +C

In scene 1 (connected to beatmaker):

# CC83 = scene 0, CC80 = scene 2
B0 53 7F = C0 00 +C
B0 50 7F = C0 02 +C

In scene 2 (connected to beatmaker):

# CC83 = scene 0, CC80 = scene 1  
B0 53 7F = C0 00 +C
B0 50 7F = C0 01 +C
N9 24 = XA 00
N9 25 = XA 01
N9 26 = XA 02
N9 27 = XA 03
N9 28 = XA 04
N9 29 = XA 05
N9 2A = XA 06
N9 2B = XA 07
N9 2C = XA 08
NA = X9

I think that might be closer to what you want.

If you want to remap the pads when in scene 0 (thor) with CC80 then you will need a 4th scene with thor connection + remap + relevant CC83/80 to switch.
