Hi Nic,

I have a new need for help.

I use a secondary iPhone SE to control my main iPhone 7 Plus looper rig via BT advertising.

The goal is to control 7 Plus GroupTheLoop sessions loading with SE using Mani Consulting Limited Velocity Keyboard drum pads. Some midi notes are learned in GroupTheLoop for that purpose.

I also use iOS switch control recipes with custom gestures to remotely set Link tempo in GroupTheLoop on each session load. That way, I never touch the 7 Plus screen any avoid and accidental tap.

Everything works quite well. I used and tweaked that code in streambyter, to force maximum velocity and filter PB and CC on Velocity Keyboard (needed for iOS switch control):

# Velocity Fixer (remote controllable)
# by audeonic
IF LOAD
ASS K0 = B0 15 # remote control event
ASS L0 = 7F +P # current fixed velocity
SET LB0 SVEL # set labels to current velocity
SET LB1 L0 +D
END

# handle remote control of velocity
IF M0 == K0 K1
ASS L0 = M2 # assign velocity
SET LB1 L0 +D # show current velocity on label
END

# fix velocity
IF MT == 90
IF M2 > 0
ASS M2 = L0
END
END

EX = XX +B # block pitchbend
BX = XX +B # block all controllers

Now, what I need are two things:

First one is that I want to use only one button/midi note in iOS switch control to set Link tempo remotely. I’ve created recipes gestures for each note (8 songs) but switch control iOS 13 allows to create only 18 switches, so I want to stay economical here. So I need a code which allow for each incoming note to also send a specific note, except for that note. For example, if I play C3, D3, etc, it also send C-2, but if I play C-2 it only send C-2. That way, iPhone SE drum pads will trigger GroupTheLoop sessions load with an additional note controlling Link set tempo via switch control.

Second one is that I need a code to prevent accidental triggering on iPhone SE, as I don’t want to load a session on a bad move. A note hold timeout for any incoming note could allow that. Then note could be sent only if drum pad is hold for 1000 ms for example.

Thanks in advance for help.

BTW I also bought MidiFire for my Lenovo T440P Mojave Hackintosh to control Ableton Live with my BlueBoard and that works equally well!!

Hi janosax ,

For your first requirement, probably the easiest way is to just clone the extra notes where you need them, just using one line remap+clone rules. Unfortunately you need to specify the note number in hex, but this table will show you the mappings and you only need to write this once. Here's a couple of examples:

# send C2 (hex 30) with a C3 (hex 3C)
NX 3C = XX 30 +C

# send C2 (hex 30) with any note from
# C3 (hex 3C) to B2 (hex 47)
NX 3C-B2 = XX 30 +C

Just set up a bunch of rules that encapsulate the logic you need.

A one second timeout before a note is sent is done something like this (obviously with 1 second latency)

if load
assign Q0 = 1000 # timeout
end

# handle note on
if MT == 90
assign LM1 = 1
send F0 7E 11 M0 M1 M2 F7 +I +DQ0
block
end

# handle note off
if MT == 80
assign LM1 = 0
block
end

# handle trigger
if M0 == F0 7E 11
if LM4 == 1
send M3 M4 M5
calc M3 = M3 - 10
send M3 M4 M5 +D200
end
block
end

Regards, Nic.

Hi Nic,

Thanks for your help and sorry for late reply.

Second rule for added note works well for me.

Unfortunately, there is a limitation with iOS switch control recipes which seems to don’t manage polyphony. I only assigned added note to control gesture, but two notes are sent at the same time, so that don’t work.

So I need to use a separate StreamByter with this code:

# C#2 (hex 31) to F#3 (hex 42)
NX 31-42 = XX 4B +C

and added rules:
- to filter every notes except hex 4B
- to send 4B after a delay, I need 10 seconds to properly set Link tempo after GroupTheLoop session load

About my other timeout need and your other set of rules, StreamByter returned those errors:

if load
#ERR assign Q0 = 1000 # timeout
end

# handle note on
if MT == 90
#ERR assign LM1 = 1
#ERR send F0 7E 11 M0 M1 M2 F7 +I
#ERR block
end

# handle note off
if MT == 80
#ERR assign LM1 = 0
#ERR block
end

# handle trigger
if M0 == F0 7E 11
#ERR IF LM4 == 1
#ERR send M3 M4 M5
#ERR calc M3 = M3 - 10
#ERR send M3 M4 M5 +D200k
#ERR end
#ERR block
end

Thanks again for all your help,

Best regards.

Hi Nic,

I also need help on this:

I want to load GroupTheLoop sessions with associated MidiFire scenes. I’ve created a streambyter notes trigger list:

# list trigger notes here
NX 31 = XX +C # Db2
NX 33 = XX +C # Eb2
NX 36 = XX +C # F#2
NX 3A = XX +C # Bb2
NX 3D = XX +C # Db3
NX 3F = XX +C # Eb3
NX 42 = XX +C # F#3

# block all other events
XX = XX +B

Then I use Mozaic AUV3 note to PC converter, so I can trigger in parallel GroupTheLoop sessions via midi notes and MidiFire scenes via PC.

The issue is that Midifire on iPhone 7 Plus manage all iPhone SE remote input messages, and output messages to GroupTheLoop. So when I trigger pads on Velocity Keyboard on SE, MidiFire scene changes but not GroupTheLoop session. so I need a timeout (delay?) on note to PC. That way GTL sessions will be triggered first and then only MidiFire scenes.

Can you add that delayed triggering (like send PC one second after note off) on the code above? And also note to PC conversion with note 1 = PC 1 etc... as that means no AUV3 conversion so less ressources.

Many thanks.

Best regards

Jean

Edit : tried with this but it doesn’t work NX = XX +D500

Hi janosax ,

I will answer your last question first, since it's easier, and come back to the others later. From your rules:

NX 31 = XX +C # Db2

This is cloning the event (+C flag), so you need to add any delay on that line:

NX 31 = XX +C +D500 # Db2

Here, however, is one sweeping rule that will convert every note on to it's corresponding program change with a delay:

9X = CX +C +D500

and will let all note events through without altering them. If you only want the remapped events to pass, just add a block afterwards.

However, you probably only want to map a few notes to program changes, so taking your original code, this modified version will convert just those specific notes to PC, delay and block all others:

# list trigger notes here
9X 31 = CX +C +D500 # Db2
9X 33 = CX +C +D500 # Eb2
9X 36 = CX +C +D500 # F#2
9X 3A = CX +C +D500 # Bb2
9X 3D = CX +C +D500 # Db3
9X 3F = CX +C +D500 # Eb3
9X 42 = CX +C +D500 # F#3

# block all other events
XX = XX +B

Also, where you show the errors above in StreamByter - are you using the most recent version?

> About my other timeout need and your other set of rules, StreamByter returned those errors:

The issue here is not that the rules are wrong, but that copy/paste inserts hidden characters at the front of all lines that are indented.

The most recent releases of MidiFire and StreamByter are (meant to be) smart enough to work around this.

Regards, Nic.

Hi Nic,

Everything is working, I was able to write my own conversion rules without issues, learned a lot and gained lot of autonomy, I’m really happy!!

Delay is not shown in Event Monitor module, so I thought there was an issue here but the delay was well applied. There also was an issue with Velocity Keyboard hosted as AU in MidiFire, delay wasn’t applied. So I used standalone version and no problem.

Also, works perfectly with associated PC conversion which changes MidiFire scenes, the 1000 ms delay allows here to other messages to be sent/received correctly.

About your rules and hold behavior, that however don’t work. Midi note On/Off is sent directly even if key is not released, but this is not what it’s supposed to do. I wish to have to press the key a 1000 ms delay before the note is sent, to avoid accidental triggering.

Thanks in advance for help when you will have some time.

Best regards

Jean

Hi janosax ,

Sorry for the delay (hehe).

First, the event monitor will show delayed events immediately they are generated, but their timestamp will be set in the future. Events are not delayed until they leave MidiFire.

Second, Velocity Keyboard may not be honouring timestamps. In the settings for that AU in MidiFire (press the 'cog'), try changing the zero latency to off if it isn't already.

Finally, I can see the hold code is wrong - I seem to have forgotten to delay the trigger event! I have edited the first post and corrected it. Maybe that will work better?

Regards, Nic.
