Hola, can recommend using the Lead Engine mode on the MB6582 - it is awesome to have 3 OSCs in a patch and still enjoy quad stereo polyphony... it still sounds like a C64, but is enhanced due to more voices... also you could try to play with the LFO and MOD sections there, combining low and higher frequency lfos on stereo panning, filter cutoff and (slight) frequency detuning... All in all, the MB6582 has fantastic sound sculpting options, which I really started to appreciate and understand only after having the hands on a few other hardware synths in the last years... Also, definitely try to build your own patches from the init patch, only you know, what you want to hear... :) Many greets, Peter

As far as I understand (and that may well be wrong :-D, please correct me)... 1) the capacitor (C part of the filter) will smooth out quick voltage differences between +5v and GND (so also the ground part is affected). For optimal voltage filtering, add a smaller capacitor parallel to the larger capacitor - a really good working pair is 2200uF in conjunction with 100nF. 2) the ferrite ring (L part of the filter) will create a small electromagnetic field (only, when current flows), which builds up a certain "stability" through the ferrite core. The electromagnetic field restricts changes to current flow. It is only necessary to "stabilize" the current flow through one wire (it flows from gnd to +5V, no need to go through the ring twice). So imho, the LC filter might help, even if you only add the +5V wire through the ferrite (you can also include the ground wire, but it won´t help much, it is the same as adding more windings to the +5V wire). Many greets, Peter

Hola, imho, the ground isolator should work fine. Another option to try before shelling out 30 bucks would be to build an inexpensive LC-filter for your 5v USB power rail, you would need to cut open an old usb cable for that, but it might be worth a try (am eliminating most noise on the power rails of my flying things with great succcess with those things): http://www.fpvuk.org/how-tos/lc-filters/ Many greets!

Hehe, true, it is a Tascam standalone WAV recorder, which is ok, probably not the best analog-digital converter on the market, but it works ok and does not crash :) Many greets, Peter

Another fav by Purple Motion :-)

Hola, there is just one manufacturer, that I cannot recommend - don´t buy any M-Audio FastTrack USB MIDI/Audio device... Their drivers under Win7/64 have certainly made me walk away from using a computer and now quite exclusively use the MIDIbox SEQ V4 :-). When seen from that perspective, that company is not all that bad :) Many greets, Peter

Great and very creative job, congratulations! :-) Normally, you are allowed to sell up to 10 MIDIboxes a year, If you want to sell more, you have to ask TK. for permission, but I have the feeling, that he will like it, especially as it is no-profit and obviously for a good cause, so I would not worry too much :-). Many greets, Peter

Did you try changing the contrast setting? Many greets, Peter

late to the show, but: congrats, looks awesome :drool: Many greets, Peter

Great find! Agreed on Spektra, but the Pokey sound is also very impressive (*mentally hugs his first "real" computer*, an Atari 800XL :-)). Thanks for posting this! Here´s my contribution, a chiptune from Mark Knight - he is a really talented guy: :-) Bye, Peter

John E Finster is right - just get and assemble a LPC17 module and one DINx4 module and read these fantastic tutorials: http://ucapps.de/mios32_c.html (#10 would be of interest). Then you can build about everything. Don´t rely on the STM32F4 support just yet. If you are interested in a finished project that allows to be used as a MIDI controller, head to the MIDIbox NG section on ucapps.de - it is a very powerful unit that allows for a lot more and implements a scripting language to control it. Many greets, Peter

Hey there and welcome :) Best way to start - go to ucapps.de and choose a project you like. Most of them are based on the LPC1769 (not the STM32F4) uC though, but that is also a fine controller. Whenever you´ve found a project, there is plenty of documentation on ucapps.de and helpful people here in this forum :-) Enjoy and have a great time! Peter

They are identical, so no problems :-).

Hi Neil, as the LEDs are driven in a time-multiplexed manner, a bit of flicker is inherent - normally you shouldn´t be able to see it, but it can be easily filmed by cameras. The flicker may be more prominent because of the used LED type (not technically proven, but as they are high brightness, maybe the light emission shuts down more quickly than with standard LEDs, when they are multiplexed...) Many greets, Peter

Great job! Sounds really nice! :-) Many greets! Peter

Hola, as far as I know, this is not (yet) possible - you could copy the track and assign two different MIDI channels, but of course this is not the same (especially if you perform live changes). (The question has been asked a few months ago and TK. answered it in a similar way... I was also searching for a solution for this problem to "layer" synths, and at first thought, the internal SEQ loopback busses might be used to do the trick, but it does not seem to work). What should work -imho- if you have a fully extended SEQ V4 or a few MIDI ports to spare: you could send out e.g. via MIDI OUT 1 CHN 1, connect your synth(s) and MIDI THRU to (for example) MIDI IN 1. Then you set up one or more MIDI router(s) and "forward" the signal (from MIDI IN 1, CHN1) to other OUTs or different channels on OUT1 (e.g. MIDI OUT 1,CHN2 - this avoids endless loops). But this solution comes at the cost of latency and MIDI ports :smile:. (Addendum - if your synths don´t have MIDI thru, you could connect MIDIOUT 1 to MIDIIN 1 on the SEQ V4, then set up a few routers to "distribute" to different channels or output ports, this might be the cleanest (and lowest latency) solution at the cost of one OUT and one IN port, fortunately the SEQV4 has up to four). Many greets! Peter

Right, the MBSID plattform offers up to four stereo engines, each consisting of two SIDs (the Sammich SID has "only" two SIDs in one engine). Have lots of fun with it - it is a great synth! :-) Many greets! Peter

Thanks, J :clover: ! Am not 100% happy with the beginning of the track though, it sounds a bit "wrong", gotta learn to master that stuff better - there currently just is not enough time for it all, will better pause for a while :) Have a great time and many greetings to northern Europe! :-D Many greets, Peter

Thanks a lot, artyman! :-) And sorry for posting so shortly after your new video, it was just ready and will probably have a longer break now :) Many greets! Peter

Hola, it has been a while due to a high workload, but could not resist playing those SIDs :smile: http://youtu.be/cipI1kn6Nsk Thanks for watching and listening! :-) Many greets, Peter

Nice & 100% analog! :-)

It could also be a failing PSU - do you use a native Commodorde power supply? Can you measure voltages on the MB6582 mainboard when it is powered on? orange_hand created an excellent infographic showing "necessary" voltages: Many greets, Peter
