MIDI filter

Hi guys - MIDI filter is great to have and very useful - however! - my first thought was, great I can use this to load the Big Bad Beats Loops into layers to play, and can reassign the key used to play them - but I can't.  You have a transpose function, but what I wanted was for any MIDI input to trigger a specific key output.  So the loop may want to hear note 60, but I want to trigger it between notes 36 and 47.  I can set the input range on the layer, but I can't have the MIDI filter output a single note.

@robertpeveler

Are you saying you'd like to be able to trigger different Big Bad Beats loops with specific MIDI keys?

Your idea to add a "convert all input notes to one specified output note" option to MIDI Filter would work, but I suspect there may be simpler ways. I'll pass this to John to seek his comments.

@getdunne thanks - well I think most of the single loops trigger off middle C, though the menus cover differing ranges.  My thought was that if you had a bass sound on one layer, you would want to play that across different notes, while keeping the mid C output note triggering the loop.  I guess though there would be an issue with retriggering, and it might be easier to use latch, but it would still be handy to trigger the latch from a low or high note to control the loop in that library.

I set the Layer transpose to +24 and can now trigger the middle C loop with C1. I can use the MIDI Filter, set transpose to +24 and it does the same thing.

 

I don't understand the goal that you say you can't accomplish. I'd typically suggest using the RX2 version so that timing is more controllable but the Loops work for me to have the main groove triggered on C1 with the way transpose works.

 

More details please 😀

@pluginguruforums Thanks - I guess I was hoping to emulate the behaviour of the other libraries - in Cloud City, for example, the loops can be triggered from a range of keys, with or without transpose, whilst in the BBB library they mostly trigger from mid C only.  But the workaround you suggest can deal with that.  More broadly, I was thinking that a MIDI "filter" could filter out pitch while keeping timing, which might have broader applications, but could just be confusing to some, I guess!

@robertpeveler I like the "filter out pitch" idea, and will probably include it in a future update. Polyphonic input could be difficult to handle gracefully, though, so I have to think about how to do that.

For remapping key-mapped loops (e.g., loop 1 triggers on C, loop 2 on D, etc.), a "scaler" MIDI plug-in (where you specify that all C's become F's, all D's become A's, or whatever) could be most useful. There are several on the market already, and adding a simple one to Unify is on my to-do list.

@robertpeveler @getdunne

There is another option to force notes to specific range: use BlueArp instead of MIDI Filter - please see the settings highlighted in red (Input and output range). The arp needs to be in "Thru" mode.

@robert-p Good point that might be what I'm looking for.

Maybe I'm missing something, but I did this in my song "Mystery" with Big Bad Beats RX2.

I selected BPM DRUM - 70 CandleLight FMx 2 RX2 and assigned it the key range of C4 to C4, and then added BPM DRUM - 70 CandleLight Fill 2 RX2 with a Unify no pitch shift layer set to D4 to D4. It worked great to play the first patch on C and the second for fills on D.

You also might want to look at MIDIBox's parameters in the interface. Where it says "Guru Sampler - Notes to Pitch" - turn that off. Now every note on the keyboard plays the drum loop at the same pitch and doesn't transpose. Then you can set it to whatever notes you want it to play on and it will play and sound correct. Since I did't make complex layer/splits for Big Bad Beats, they are all set to transpose up and down the keyboard when you play different notes - but you can turn that pitch change via keys off. 

This is based on using the RX2 version of the library. Audio Loops can do the same if you go into Guru Sampler and make sure it is set to "Unpitched" in the Master section instead of pitched.

Thanks - all helpful suggestions.  However I think John gave another illustration in the livestream on Saturday as to why a MIDI filter which suppresses note number would be useful - it would make it easier to use microtonic to drive the vocoder, without switching the alphabetical patterns.
