if you want to address a huge number of LEDs have a look at this: http://www.midibox.org/forum/index.php?topic=5626.0 As far as PWM for dimming the LEDs is concerned, it depends if you want to dim each of them individually or if you just need to adjust overall brighness or RGB balance. I am currently working on a (hopefully) very stable solution for the latter problem, based on some additional hardware and a small modification of the DOUT board. Will post results if successful... Cheers, Robert

Hello Forum, Hello Thorsten, my Monodeck II MIDI controler uses two core modules to drive LEDs, capture pots etc.... So, DOUT modules are connected to both modules for controling a lot of LEDs. Additional hardware allows to dim R,G, and B of all LEDs based on phase width modulation of simple oscillators.It works somehow but is far from being perfect since it creates all sorts of flickering and moiree effects as a side effect of five clocks sources running free. I think there is a much more elegant way: The three phase width oscillators shall be replaced by three astable oscillators that are triggered by one common clock source and this clock shall be derived from the clock oscillator of Core 1. Core 2 shall be slaved clockwise to Core 1. According to the microcontroler data sheet it is very simple to achive. But before reinventing the wheel, i'd like to ask if someone here allready did this and if it works like expected. ( idea: Microcontroler 1 provides clock on OSC2 output, Microcontroler 2 gets this clock signal on OSC1 input, MIOS needs to be altered to reflect oscillator slave mode on Microcontroler 2. Microcontroler 2 puts out Clock/4 on OSC2 and this is used, maybe after more clock divisions, to drive the LED dimmers. This should create a 100% flicker and moiree free solution...) comments, ideas, suggestions ? Thanx, Robert

I thought about this but realised that then again I would end up staring at some kind of display. And this is what i want to avoid. I figured out that I do not need so much different sounds on stage and that it is more important for me to spend a lot of time designing each single sound well enough and to work on the grooves and effects. In the stage situation I am fine with a limited amount of sounds and limited access to parameters because I do not want to end up with endless varitions of a sound but more focus on structure. For this task I do not need the display. The main element is the 8 channel / 5 slot matrix which is my playground for each single piece. I have enough to do on stage playing with the possibilites of this matrix. The control over some sound parameters is secondary. Currently I work on the assignement of the three knobs and the toggle button I have on each channel. I made lots of efforts to create interesting morphing sounds but finally figured out it does not help me so much musically. I was able to morph from some sine wave plonc! sound to variuos hihats on one channel, but then I realised all I really need musically in this channel is a hihat. So i dismissed that complex morph in favour of simple hihat parameters ( fitering, decay, hold time ) and the result is much better. There is always this impulse to add more and more features, but I am quit happy that Monodeck II forces me to really think about the structure instead of getting lost in possibilites. Robert

Hello !!! Yes, it is done. After almost one year of hard (brain) work. I will spend all september with the preparation of a new Monolake live set which is to be performed using the Monodeck. The plan is to get rid of the computer on stage and to run the show entirely from the hardware controler, even without the need to watch a computer screen. I might contribute / answer questions here at the forum but I am not sure how much time I will find for this. We will see.... Thorsten, thank you for all your work & knowledge - much appreciated.
