Have a strange tech issue, and looking for some insight.

My main rig is a Win10 64 rig. Well, the other day, inexplicably my Tau stopped working. The PSU shows up in device manager, but it can’t connect to EigenD.

I have tried reinstalling the drivers, EigenD, tried different USB ports, Different versions of the driver, tried the “with audio capable firmware” driver, and the with “extension mode firmware” driver, versions 1, 1.0.1, completely uninstalling and scrubbing drivers and files, and reinstalling, 8 different USB ports and cable combos… Nothing.

Move it over to a laptop, running same versions, and everything works. It just simply will not work whatsoever on my main rig, and WAS working fine up until Thursday. No, no windows update in that time, and no other USB device is having trouble.

So, before I have to throw a “hail mary” and completely reinstall my OS hoping that the problem goes away, can anyone think of ANYTHING that would cause this? Have never had this problem before, and can’t duplicate it on any other machine. Everything looks like it checks out hardware wise, and the device detects and clearly the driver loads, but EigenD simply cannot see it on this machine.

Any ideas would be appreciated. I’d rather not spend a day or two reinstalling all my audio stuff because of one weird driver issue.

One of the keycaps on my Tau has gone mysteriously missing. I just noticed it this morning, and spend a couple hours going over the floor carefully looking for it. No dice.

Is it possible to order a replacement keycap? Couldn’t find anything on the site.

Geert Bevin, I recently stumbled across a video of you doing a presentation where you had a strummer setup going into Cubase 8 and had managed to get per note expression working. Well, I recently moved to Cubase 9 Pro from Live for a number of reasons, including the possibility of per note expression.

Unfortunately the video quality was not fantastic, and your explanation of your setup was kind of lost in the general room noise.

I’m wondering if you might share some details on how you set up the track / mapped the alpha, because I am more than a little lost in the track settings.

I’d like to get the breath control / expressiveness working like your setup seemed to be doing. It must have been a while back.

Any advice would be much appreciated.

In the meantime, I’ll keep poking at all these new settings and see if I can figure it out. LOL

I have some hardware synths from the early 80s with very early midi processing ICs that are terribly slow, like a DX7, Prophet, etc. Thing is that the chips on these crawl compared to modern offerings and they only had 128b as a buffer.

Even with data decimation taken to the max 100ms, the eigenharp floods their buffers in two keystrokes.

So I was gonna write a midi filter agent to control the buffer size and increase decimation to up to 200 ms, but BEFORE I go and do all that, I thought it might be smarter to ask the crew here is they have a better solution?

I’m running the tau with a headless raspberry pi with a lightweight midi setup, so patching it through a bunch of third party software is probably a solid “No’.

Maybe puredata because it’s lightweight.

Wondering if Mark or Geert have had to deal with this before?

I need some help with the midi converter windows. When I assign the strip or a key to any CC the most infuriating thing happens and I can’t seem to stop it.

The instant my finger leaves the key, it reverts to a default value. So imagine that you wanted to map the strip to your volume control, no matter what options you try, the second your finger leaves the strip, the volume resets to 0.

This is the same with the buttons.

I am trying to set up a few buttons to work as CC for controlling some parameters in my VST, and it is a nightmare. I get the CC messages as long as I hold the buttons, and when I release them, they send everything back to 0, as if they were momentary toggles.

The option to return to origin in the matrix editor appears to do nothing, and in my software it doesn’t matter if I set anything to relative or absolute mode in the VST. Doesn’t matter.

How can I stop this?

If I set a volume, I do NOT want it to go to 0 when my finger leaves a key.

Very frustrating.

Anyone know how to do this? Is there some black magic I have to invoke in workbench?

I’m having trouble building linux EigenD for 2.1.5 or 2.1.6 on arm7 (raspberry pi – arm 32bit).

in both cases, the compiles all work fine, but when the linker goes to assemble things, it chokes on the pico decoder.

tmp/bin/libpico_decoder_1_0_0.so: error adding symbols: File in wrong format

I’ve had a look through to see if there is any x86 specific compile instructions in the make config, but I am afraid that I’m not too familiar with SCons. I’m a gnu autoconf cowboy. I also don’t see anything platform specific in the code.

I’m sure that all I need to do is add a linker flag, but not sure where or what it is expecting. Wondering if anyone might know what I am missing.

Where in an SCons build can I specify compiler and flags? I’m sure if I just passed an explicit –arch=armv7 that the linker would be happy.

I’m still running 2.1.2 which builds fine and does what I need, but it would be nice to know moving forward what I should be doing.

If anyone has any insight, please lemme know.

So I finally got around to playing with the arranger to try to sequence a bass track.

It’s pretty cool, but for the life of me I cannot seem to figure out how to set the note length. So for some of the more evolving bass sounds, the sample gets chopped on the 1/4 note default.

I see there is a way to do this in belcanto, but I am frankly very bad at belcanto and find it counter-intuitive.

Can someone point me in the right direction for the documentation for this?

There are some videos on youtube, but the sound is so low, that even with my speakers cranked, I simply cannot hear what they are saying.

Thanks in advance!

Hi Guys,

Dumb noob problem here. I am struggling unsuccessfully to add an illuminator to the factor Tau setup so I can light up frets on keygroup one.

The online tutorial is of course written for a simplified pico setup, but it’s easy enough to follow and adapt for a tau.

So i get the whole thing set up, including a new kegroup to access a new talker that sends the commands, but here’s where I get utterly lost.

I go into my new keygroup, select the green color, then what? If I do anything that exits the advanced mode, try to select keygroup one with the mode button, and then try to select any keys, nothing happens at all. As near as I can tell, I have set everything up right, but something about the setup on the tau means that the physical choose operation goes out of scope when trying to select keygroup 1.

Pulling my hair out here trying to figure out what I’ve done wrong, and for the life of me, can’t find anything. I need a more experienced user to maybe explain to me in baby steps what is going on, and what I’m doing wrong.

The pico tutorial just isn’t cutting it for me.

Scroll / EigenBrowser problem with Tau

Wondering if anyone knows what the issue might be. When using the tau, and trying to browse sound fonts or AU/VSTs I can get the browser to display on the monitor by clicking the browse button for that particular setup, but….

Scrolling does not work. Key X/Y does not appear to be bound to any scrolling or selecting behavior.

Using windows btw.

Tried on two diff machines, and nada.

Using factory setups.

Any ideas?
