Eigenharp Google+ Community Archive

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 ANYTHI...

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.

It's been quiet here lately, so I thought I would just say Hi and see how everyone's 2018 was going, or if there was anything interesting going on for any of you.

I am wondering if there is any updated doc anywhere on the agents in the community version of eigend? There have been a whole lot of agents added, but many of them are a complete mystery to me - what they do, how to confiture them, and so on. Like, what does the live pad agent do? What do the controls mean? I see an ableton push agent, but it has no parameters to edit, so how does it get used? I can't find any doc on most of these, and sadly there are no readme files in the source dirs that provide clues, nor can I find anything online that lists these. Is there a documentation resource I am missing?

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've been using the tau basic midi setup a lot on my pi because it's so lightweight and loads fast. I decided to add tonic lights as a visual aid, and for the life of me can't seem to figure out the belcanto, or how to do it in workbench. Its a little different than other setups so examples I find online aren't quite working for me. Just wondering if anyone has done this with that setup and how they did it.

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 f...

I have a general question for the Tau and Alpha users in the group. Do you use the standard key mapping in your keygroups, or do you have another preferred mapping? I ask because I find playing some chords with my left hand quite awkward. I have to use one finger often to play two keys, which can be very tricky if you have dynamics mapped to the Y axis of keys. Right hand is no problem because of the orientation of notes, and chords all line up neatly. So out of curiosity, what style of keymapping do you prefer?

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 any...

I recently built EigenD for raspberry pi, and it works great for my setups. (I don't use the convolution engine - which it doesn't have the power for), but my dream of using the Tau headless are still out of reach. EigenD will not launch without X running, so a headless setup where I just plug in the Pi and go doesn't work. I still need keyboard and mouse. So I got to thinking, before I try building something myself to fake it out, that I should check to see if someone else has done this already. Mark Harris for example. More or less I'm wondering about running the core of EigenD as a daemon / service, and if its possible to have a CLI interface to it. It would be wonderful if I could also enter Belcanto on my tau and not have to worry at all about looking at a screen during a performance. Has anyone attempted anything like this?

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!

I was wondering what the current status of EigenD and the USB driver for the basestation are for linux? I've combed the forums, and the last entries seem to be for last year, and not exactly related to the subject at hand. I see that linux is mentioned all over the source, but it's unclear if it is currently able to build and run. So I was gonna try it out on a new Pi model 3 running ubuntu, but wanted to know if anyone else is more up to speed on this and find out if there's any gotchas I should know about.

Anyone got any suggestions on extending the Tau endpin? It's awkward for playing seated and I'd like to put another 30cm or thereabouts on it. Tons of cello endpins for sale out there, but nothing with the somewhat unusual design of the tau's endpin. I read on the wiki that Eigenlabs was selling cello endpins for about £100, but stopped making them. I might just print something (I've a 3d printer here) as a sorta adapter for classic cello endpins, but was wondering if anyone else has already done something similar or has recommendations for existing stuff.

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 expla...

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?

Word to the wise. The documentation on building under windows is erroneous and incomplete, and does not reflect current status of the asio sdk, and Visual Studio deps. I just got it to build under VS2015 successfully and it works great. I would if it were possible like to amend the build instructions for those that ran into the same pitfalls as I and whom may not have the experience to sort it out. The bld.cmd needs to be augmented to set proper environment variables in later versions of Visual Studio, and the instructions for including the steinberg libraries is incomplete as a number of headers in base need to be included also. Who do I bug about adding some documentation to make this easier for the next fella? http://bld.cm

Need some advice with ableton. In short, the midi rigs do not show up in the ableton preferences under Windows. All other midi controllers show. So I can't use my tau as a controller in ableton. Is this a known issue and are there work arounds? Same behavior on 2.1.0 and 2.0.74. Have confirmed that I have midi out 1 selected as my instrument mode (tried with midi out 2 as well), and have confirmed that in my midi rig windows that there are reasonable settings in the matrix. It is honestly like the midi device is not available to applications other than EigenD. Is there a way to connect the Tau midi output to ableton, or something that I am missing?

I'm the proud owner of a new Tau and am completely in love. Still learning things. Worked through the tutorial videos, and the somewhat... um... sparse documentation on getting started, but I am up and running, and discovering new possibilities daily. I just wanted to say hi, and thanks for all the information I found via this community. Still struggling with how to do a few things, so I may ask you all a few very dumb questions from time to time, but everyone seems super open, so hopeully you won't laugh too hard if I ask something ridiculous. Great to see such a vibrant community!
