Hi there. This thread on the teensy forum shows the build, and also some improvement. forum.pjrc.com/index.php?threads/teensy-apa102-pov-poi-pixel-poi-build-tutorial.30020/

Could have used a cv from envelope, yes, but hooked it up to my homebuilt sequencer that has glide function per step if wanted. The glide is a bit strange wrt amount of each step having movement, but I like it! It's module on the second row, right hand side

Hey there, there is a tutorial and lots of discussion about improvements on the teensy forum: forum.pjrc.com/index.php?threads/teensy-apa102-pov-poi-pixel-poi-build-tutorial.30020/ it will really help. ❤

But I want to know what is the board or something module that you used sir.?

Last question sir.. is this for teensy 3.1 only? Or I compatible in any teensy?

So, people in the forum have used teensy microcontroller 3.2, LC, 3.5 and 3.6. Looks like one person has tried 4.0, but I can't see the result. Perhaps join the forum and ask the user there to see if it worked?

Amm sir how to insert images in teensy? Is this have a settings?? Inside the installer?

Hey there, the code on github should get you going: github.com/mortonkopf/Pixi_demo

@@mortonkopf8265 Thank you ! How do you like this max11300 chip?

@@musicphilebd9862 it's great at what it does, stable cv output, but it's a faff to code. Also seems to be alittle picky regarding microcontroller speed, so dialled it down to 24mhz and seemed to work much better for initialisation. Once you get the hang of voltage range and bit to voltage conversion, it allngoes very well

Hey there, that's a homebrew euclidean sequencer. Four channels, using a teensy microcontroller as its heart.

@@mortonkopf8265 isn't that the one at the bottom left? kind of looks a bit like a greater euclidean circles. what about the small one on the top left that looks like it's transposing berlin school?

Ah, yep, sorry about that, it's another home brew sequencer. Based on a teensy microcontroller again, it's just a simple 8 step. Push the buttons in order of progression for 8 steps. Not amazingly versatile, but does exactly what I need.

Oh hi, that's a home brew euclidean sequencer.

@@mortonkopf8265 fantastic Thankyou it’s gorgeous

Thank you!

Hehe! I really should have put a bit more in the description box!!

@@mortonkopf8265 it's good all the same .. it will impress the right people 😁

@@sea-saw2654 well, there are two points about that comment ....

hey there. Yes, if you want your diy midi device to sync to a clock, you have the midi in stream look for midi value 248, this is a clock value.

@@mortonkopf8265 Do you mind if i DM you? i have this project which I am trying to figure it out and cant seem to get it working!

@@closerau you can contact me through the Teensy forum, send me a message there

@@mortonkopf8265 awesome will do

@@mortonkopf8265 No problem, is it the same username?

hi there. This is a bit old, and you can now get much better led strips / pixels to build these with. the updates are here: forum.pjrc.com/threads/30020-Teensy-APA102-POV-Poi-Pixel-Poi-Build-Tutorial

hi there. yes, its DIY using a microcontroller call a Teensy, same to programme as an arduino, just much more powerful. there are some updates to the build docs here: forum.pjrc.com/threads/30020-Teensy-APA102-POV-Poi-Pixel-Poi-Build-Tutorial

hi there, this was really a proof of concept for a hybrid midi eurorack rig. It uses the a midi clock / sync signal from the eurorack clock outputter, all the sounds are generated by the oscillators in the korg, as well as the korg doing the filter and envelope. The sound is output at audio level to a mixer. it would need to be amplified to be at eurorack level.

hi there. Yes, using 5v off the eurorack rail. I spliced a eurorack 16pin header into a usb cable and plug the cable into the front of the Korg. You can see the cable going in the front in its usual place.

@@mortonkopf8265 Brilliant! Thanks for getting right back to me. I'm going to try this tonight.

Hi there, you can find a write up here: orchardelica.com/wp/?p=845 I have not written up the electrical aspects as they are the same as everyone else has done. The difference is the orientation of the potentiometers, and wiring the inputs up to jacks

@@mortonkopf8265 thanks, i know that website but there so many mods from everyone else that iam confused from it :( do you have a links where you taken from

interesting idea, I don't know the answer. The ribbon is plug in, and the NTS1 also has a calibration method to set up the ribbon keyboard, so in theory i guess you could. I don't know if the ribbon works on resistance values or something else though. Sorry.

I removed the ribbon keyboard and am going to attempt to add jacks right to the board there so there's no sidecar setup.

Hi there, you can find the source code and a discussion on improving the poi on the teensy forum here: forum.pjrc.com/threads/30020-Teensy-APA102-POV-Poi-Pixel-Poi-Build-Tutorial

You might be right! Hehe

Nice one, will be useful.

Got it down yet?

These are found with an Internet search of "rgb rotary encoder" . They are originally from Sparkfun.

Hey, glad you like it. At the moment it can default to external midi clock when it detects a clock signal. Still planning on adding the external clock voltage input and jack. Isn't too difficult to do, just finding the time is tricky. The midi clock option is in the code on github

@@mortonkopf8265 Thanks for quick reply. I'm stiil learning and Yes, adding clock in would be great, looking forward for the update sketches , off course iif you have spare time . Meanwhile I can live with default midi clock. :) Already sub and waitin for the bell. Thanks

Glad you like it. My approach probably isn't liked by a lot of people, as my system is hybrid, using midi as well as cv across the modules. The 3.5 midi approach is really useful at saving space, and I really want to leverage what I can from the kit that best serves me. So, in comes the Korg. I have just uploaded different sounds, and really like the Chords one.

Hey, thanks for that. I appreciate the comments. The code is available on github, and I will try and get a short write up done, at some stage. Who knows when....

Hi there. These are the adafruit neopixel rings. They come in different sizes, these ones are 16 leds.

have a look at some of the circuits posted on the Teensy Forum, you can programme teensy the same as an arduino, using the same IDE. For just triggers, it would be very straight forward for something basic, the Teensy will output 3v High, which isn't always acceptable for some modules. some arduinos use 5v logic, so might be better for just triggers, but I have not had any problems with 3v high triggers on my eurorack. A teensy, some jacks, a couple of resistors and diodes for protection, and you are there.

If only there were time! Its not really up to spec for selling. The outputs are simply protected with resistors and diodes, and there are a lot of things that would need upgrading to make it suitable. But thanks for the comment.

@@mortonkopf8265 thanks for showing your stuff!

ha! yes, it really is great fun and seems to produce a lot of new odd beats every time I turn knob. Thanks for the nice comment.

Do it! Teensy code is here: github.com/mortonkopf/Teensy-Euclidean-Sequencer-Eurorack

Me too! Thanks for sharing, Morton

You rock!

funny you should say that, I have converted the euclidean sequencer to eurorack. its the white unit in the top left on this video: th-cam.com/video/gJTBsC1AAsI/w-d-xo.html It has four channel output, with both trigger and inverted trigger (the off steps are triggered through the second output per channel) I will try and get a write up done. As its only for my use, I used 3v trigger and gate signals, not 5v.

hi there. that is what i was oping to do with also, similar to removing the ribbon t=controller on the monotone and replacing with a bunch of 3.5mm inputs. Unfortunately, the nts1 has a trace running below the ribbon controller and the connector plus resistors and caps for the ribbon (grouped at one end, but still underneath). it might be possible with careful drilling to squeeze in 3.5mm sockets next to the trace, but i wasn't willing to risk it.

@@mortonkopf8265 I'm going to try! ;-)

Definitely makes creating beats even more enjoyable

Seems pretty good so far
