Today I try connect not only portable setup, but also some studio synths.
I used 3 DIN inputs, 2 USB inputs (sequencers and controllers) and 5 DIN/TRS outputs (synths).

I need create routing between all controller and all synths (all to all). Before you ask - yes, it make sense, because sometimes I use two sequencers to control one mono synth, and sometimes I use one sequencer to control few sytnths (in example Keystep Pro). Another example is knobs controller - it's used for all devices in different ways. 

When I created 26 routings, it didn't allow me to add any new routing. IS THAT LIMIT FOR MRCC? It's not large setup, there are still 3 empty inputs and 7 outputs...  There was even no any modifier.

Been looking to get my Keystep and NDLR to work together and can't quite figure it out. I may be missing something to get them to communicate. Any help in this matter would be greatly appreciated!

Floating an idea, Would many people be interested in the concept of Linking 2-3 MRCC's,
Like DMX universe's I'm thinking (1) for Studio stuff and (2) Live rig Rack.

As of yesterday, I am the happy owner of two lovely MRCCs.  With roughly 30 devices to connect, I'll finally be able to have a cohesive system, after giving Hosa the remainder of my money for cables.

Anyway, in doing initial setup, I found that my DAW sees both units, 12 ports each, and they are differentiated by a number 1 or 2 (for example MIDIIN7 [MRCC 2]) that the computer apparently supplies based on the order the unit is discovered, which can obviously change.  Since MIDI instrument tracks in my DAW need to have a specific port assignment, these ports will need to be consistent.  Is the only way to keep them consistent to always boot each MRCC in sequence, or is there some other way of letting the computer identify which is which, more than just the general device name?

I have a terrible time making the rhythm editor work.  Making the lowest note value in the pattern editor a rest would be a super convenient way of easily working with melodies.

Please?

This is the most fundamental think missing for me .

Hi there,

after spending some time with the MRCC and being a hardcore MIDI Patchbay user (mainly MIDITemp MP series, iirc not known in USA, but in Europe) I think the MRCC is up until now the device that gets the closest to the MP series and add some modern features, but still leave a lot do be desired.

If I should split up that text in 2 parts, one for the feature requests, please let me know.

I will not comment on the hardware, since that cant change for now, so I focus on the Firmware. Here are my thoughts:

      

• default display page should be preset and selector, not activity
  
• Routing DIN ports should have a special mode or should be not so easy to adjust, like hold input button
  
• Naming of presets possible?
  
• Preset save load should be at main page too
  
• Why no routing adjustment in the second page?
  
• Is there a routing overview page?
  
• Port Naming as interface could be better
  
• Port Names are not seen in MacOS Audio MIDI Setup
  
• Should show display actions while doing routings, ATM it’s somewhat  blindfolded, especially when routing USB ports
  
• is there a Port Reservation function for USB Host ports? If no, there should be, like on iConnectivity interfaces
  
• Sysex filter is missing
  

• PC Filter should include both bank controllers, independent of CCs
  
• Add a shortcut mode for preset select, like holding Y and typing in numbers
  
• Add USB storage support for USB sticks
  
• add a backup function for an USB stick on host ports
  
• add USB Host port reservation feature
  
• Add a Sysex filter
  
• Since Note modifiers can be used for drum maps, so please add a drum map feature with cakewalk style maps to import (simple text files)
  
• Labels should be saved independent from a preset (global)
  
• Combine channel mapping with channel to port mapping, so a channel can be mapped differently to different outputs
  
• Velocity processor should be port based also
  
• Note Alter should be port based also
  
• In addition to Ports install a device management. Each device gets a Name, descriptor for Clock send, Receive or Clock Priority and it then can be assigned to a port. If you rewire your setup you don’t have to reprogram the complete routing, just assign the device to another port
  
• Virtual cable Feature. Instead of assigning filters and remaps to a certain port or channel it can be assigned to the specific connection between 2 ports.
  
• Panic function should have a label on the case
  
• Add a button/panel lock function
  
• Add a startup delay for devices that take longer to boot and should receive commands
  

Since the last thread dealing with that problem was maerked as "solved" (which it wasn't) I open a new one.

Jesse said, that not all keyboards work, and that should not be the case, since there are standards for USB HID devices and if the HID descriptor says "Type: keyboard" it should work.

I encountered the same problem and as with the NDLR, it seems to be another USB descriptor issue. Maybe the library used is the problem, but it needs to be adressed and solved.

I tried that with my mini USB ASCII keyboard and that didnt work, also my old Mac Extended II Keyboard with iMate ADB to USB adaptor. Both keyboards work on the Akai Force and on the Roland Fantom (where it is not officially stated to do so).

So I tried my cheap asian 9key keybed and that worked. So I did another USB readout, and it seems that the library only accepts keyboards with the Microsoft OS Descriptor.

Here are both readouts, with the essential parts marked in red.

9 key keybed, works:

Greetings, all!

Done a bit of searching here and there and just thought I’d see if there’s any new/better ways to connect the NDLR with my Eurorack system or if the CV.OCD is still the way to go?

Thanks in advance!!
John

I'd love to be able to set a MIDI clock offset per port. I have a slicer pedal, and it needs to be tied super tight to the rhythm. It would be nice to be able to set an individual clock offset for that port to dial it in.
