Thanks TB. I did check the linnstrument modes and I am on the latest revision with the cool lights etc. (2.1.0 I believe but whatever R. Linn just released).
I will go back and try the demos again I guess. I will try to provide more details if it still doesn't work.
All good here, MPE demo patches, LS with 2.1.0 (0.49 if you press on 210 
at what level? X? Y? Z?
Use the LS presets to be sure you are on MPE.... sorry if its too obvious.
Thanks all!
I will try that tonight @keyman keyman. No insult at all, I just got the ls like a week ago and I been splitting my time between mixing......that plus missing a few brain cells from college days (wink wink)
Hey all!
Just got my axoloti late last week and have been trying these patches out with my linnstrument (which is what finally motivated me to get this awesome sound board). As such, just signed up and here's my first post.
First, these patches sound great, MPE is working, and I'm totally digging noddling around with all the expressivity! Thanks to TSG for patching these up and to the creators for building a great product and setting up a place for a community to grow.
Two questions:
1) I haven't had success powering the axoloti from microUSB and then using the axoloti as midi host to power the linnstrument from the full-sized usb on the axoloti. For the moment I'm powering the linnstrument externally and using a 5pin midi cable to connect the two. Is there anything I need to setup on the axoloti side to have it be powered from USB and to also use it as a host?
2) I can't seem to get my axoloti to respond to the CC faders (this is true in both the buzz and the karp engines) on my linnstrument. I have the split setup (I followed the youtube video) and assigned faders to cc12-19. Any thoughts on what else I might be missing? If I plug the axoloti into my comp, run the patches live and tweak the parameters with my mouse they patch responds just as expected.
Cheers and thanks!
Welcome to the world of Axoloti!
I'm glad you like the patches. Axoloti is brilliant for designing sound engines for the Linnstrument and with the CC faders you don't even need any other gear to control your sound engines.
Re 1)
What happens when you try it? Does the linnstrument show any signs of live (maybe a short flicker or something like that?). For me it always simply worked, no matter if I powered the axoloti from a computers USB port or from a cheap smartphone charger. Can you power up any other gear from the axoloti? The linnstrument has a low power mode. Does that improve anything (you could try to enable it while externally powered, then try USB power)
Re 2)
I'm not sure on which channel the second split sends the values from the CC faders by default. My setting can be seen on minute 4:19 in my video. If I read the code of the corresponding axoloti objects correctly, you should send the CCs on channel 1. Maybe your right split is configured for another channel? Can you try that?
Thanks for the quick reply and friendly welcome!
Nothing, I tried powering my axoloti both from a smartphone charger and from a computer and I tried setting the linnstrument to the low power setting. I'll try again tonight.
ahh, could be that I missed this - I certainly didn't purposefully set it or change it. I'll check tonight.
figured out the cc - you were correct that I didn't have the channels set up correctly. I think I did it differently than in your video by selecting the top row in the leftmost three columns (one channel, main chan, midi channel 1).
Still no luck on using the axoloti as a usb host to power (let alone recieve signals) the linnstrument...
Just figured it out. Tried a different cable (I had been trying the one that came with the linnstrument...). New cable gave me power but no MIDI. I had to reboot the axoloti without a 5din midi cabled plugged into MIDI IN to have the axoloti recognize that it should recieve signals over usb. Good 'ol reboot to the rescue.
Thanks again for the patch and your help! Once work gets settled down I hope to get around to building some more MPE patches to share with the community.
I got my LinnStrument yesterday, and already have easily spent 5+ hours noodling around with the Buzz patch. Caution: Very addictive!
Wohoo, Roger Linn mentioned this project in this months newsletter:
http://www.rogerlinndesign.com/LinnStrument-News-Sept-2017.html
Apparently the Axoloti is by far the cheapest hardware sound generator for the LinnStrument. Cool!
great patches! btw. i used a qunexus in channel rotation mode, starting on channel 2 and it makes a pretty decent "mpe" controller. nice and cheap!! (you can even select some general modulation sources from expression pedal etc. that will be sent on channel 1)
I'll get a Roli seaboard rise 49 tomorrow... I'll definitively try these !!
[EDIT]
Just tried it.
It's great... there is a lot of room for experimentation.
I think that I'll experiment krate filters (lowpass and/or highpass) on the continuous controls (pressure and slide).
Hi, mpe enthusiasts,
i added an mpe directory to the axoloti/tiar repo:
Library->community->tiar->mpe
You will find there a mpe version of the "commuted waveguide violin" (with an improved attack - velocity controlled - and reverb).
I'll adapt many patches there in the future.
The sub directory
Library->community->tiar->mpe->sbrd rise
will contain mpe patches more specifically designed for the seaboard rise mpe controllers.
For the moment, it contains a special "commuted waveguide violin".
As I played with the seaboard, i wanted to do big "virtuoso" glides...
so, almost no quantification...
and a lot of false notes.
I'm not Jordan Rudess !...
I don't want to switch on the note quantification on the seaboard (even if the quant algo is nice). I want to glide AND play right with no effort 
The seaboard sends the information about the vertical position on the keywaves as the "timbre" CC74...
So, in the axoloti patch i added a soft quantisation object that is controlled by the vertical position on the keywaves.
So if you are around the middle of a keywave, the quantification will be more effective than if your fingers slide at the top or bottom of the keywaves.
With this simple trick you can play "virtuoso" without too many false notes.

[UPDATE 04 jul 18] Polyphony extended to 5 voices.
I would like to use my Novation Launchpad X with The Slow Growth's patches. This 8x8 pad controller is not natively MPE but it does have velocity, and polyphonic aftertouch and I have tried it with some other patches, including a MIDI monitor which shows the poly aftertouch messages are coming through.
I'm a complete beginner with Axoloti so I really need some guidance on how to get this working with Buzz and Karp.
JeromeB says he has it working with an MPD32 so I'm hoping this can be done with the LPX.
Any hints would be appreciated, thanks.
I'm getting the same issue with lack of control from the CC faders on the Linnstrument, but I've got the same settings as you have in your video. I can change parameters in the patch and they affect the sound. Should I be able to see the parameter values change if I adjust the CC slider values on the LS when I'm watching the patch in Live view?
Hello ! I just get a Linn Instrument 128, and i would check your MPE patches.
Thank youv ery much for your contribution, but, i can't find the patches in the community library.
Where can i get it, please ?
Greetings
Yves
Hi Lafont, see in the title post:
The patches are now in the community library. Go to File->Library->community->TSG->MPE to try them out for yourself.
Almost 5 yrs later, these are still some of my favorite MPE patches. Has @TheSlowGrowth written any MPE goodness for other platforms in the interim?
