Very nice and thanks for your efforts, phunk!

it looks great in a white case with a "natural" panel and flathead leds ftw. very nice! don´t forget the feedback mod - it is a cool add-on, at least for the 8580s - dunno about the 6581

looks very nice, especially the time-graphs! /got to stop reading this thread, says my wallet.

led rings around encoders are supported - go read these sections on ucapps.de: pic based core, stm32 based core, din and dout modules, decide for a project you want to build - read the wiki, then ask specific questions :)

well and don´t tell the chinese, that sids, when properly crushed, crumbled and boiled with chicken eggs are actually increasing sp%$m production

Nice! Did i ever say i like flathead LEDs a lot? :-) Edit: did not see it properly as it is quite unsharp - is it lexan instead of LED heads? That is interesting...

bah all those clones will never reach the superior audiophile qualities of those ceramic cased 6581r1s - they protect against cosmic rays, you know! http://www.digital-circuits.org/sid/CSG%20Micrographs/6581R4/6581R4-fulldie.jpg

Non-programming-approaches: 1) Research better alternatives :-) 2) If you look at my photo tut of the mbseq v4, you can see how you can separate the cs (in your case a minimal one which will fit easily on a stage piano) from the core. The advantage would be that you can build a full cs (with displays and bling) later on, when you are ready for trance music and a full blown seq v4 again ;-). The disadvantage would be that I think, mbseq presets cannot be loaded properly without display, so I would advise against it... Programmig-approaches: 1) Read the previous post - just build a core32 and a din module and get get ready to hack some code as suggested :-)

whoa - my estimate is that they will be worth more than their weight in gold in a few decades :-)

Great and thanks a lot to you and mr ohm senior :-) I will use then 13pcs 220R resistors in parallel giving 16,92 ohms which will cause 296 mA load according to the formula, that is close enough :-)

methinks that there must be other solutions out there that don´t involve programming, but if you want to do it - have a look at core32 tutorial 4 (sending midi): http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Ftutorials%2F004_sending_midi%2F in app.c, a MIOS function named SendCC is called like this: MIOS32_MIDI_SendCC(port, Chn1, 1, midi_package.velocity); if you combine that with code from tutorial 10 (DIN) which executes it when you press a button, you are almost done...

rethinking this... is there an easy way to create a 300mA load on the 5V chain so that I can test prior to buying one? I have lots of standard 0.25W resistors flying around, how would I chain them correctly?

Quoting the message phil cced me, they said 60ct per piece for 100 (as he did not inquire for more) and also the following: Del. time: no stock available - new production in week3-4/2011 that means some time before unbuttoning your gfs err unpacking your knobs :)

gets cheaper when we do a forum bulk order of 100pcs :)

just for the theoretic possibility, you could do that with a core32, one din module and very few buttons running an unaltered mbseq... but there surely are better solutions out there to send preprogrammed batches of ccs... on the other hand... deep inside you know, you want a full mbseq :D edit: it would also be a good project to learn mios c programming... it is not difficult to send predefined CCs to midi ports and TK has written very nice tutorials... then you would only need a core32, a din module and as many preset buttons as you want to have... it gets a little bit more complicated if you want to configure which ccs to send within the unit...

is all of your software and gear able to respond to midi ccs? then maybe a mbseq would do the job - i have not finished and integrated mine but have the feeling that it could do the job - so i am very interested in further comments, too :-). edit: reasoning... dirty copy and paste from the SEQ V4 manual: PRESET: this button opens a dialog which allows to select a preset file (left side), or to store a new preset: ... Advantages of using preset files: You can store your favourite track configurations, melody lines, drum loops, etc. in separate files to recall them laterYou can prepare drum maps for different instrumentsYou can prepare CC setups for different instruments

Viewing the slow LCD display updates next to VFDs has become quite a burden lately :-) I haz made some successful color-altering tests with color foil, which creates great red character output from a standard vfd... Of course it is not a cheap modification, but the mb6582 is my fav synth currently... so the question is... Has anyone successfully installed a 4x20 VFD in a MB6582? Noritake advertises some as LCD drop-in replacement alternatives... Eg. CU20045-UW5J Datasheet: http://www.farnell.c...heets/14273.pdf It seems that it will physically fit... but will it cause too much load on the 5V chain (275 mA typical)? I have a standard C64 PSU, 9V only option on baseboard and 8x8580 installed. Thanks for your opinions, Peter (If this works out, I will update the photo tutorial, of course :-))

Hi Ben, great to hear your build went fine ;-) The sammich VU meter is just for bling, this one has a real purpose :-). Differently to the sammich, the meter mode displays the modulator output values - you can experiment with this turning the LFO speed and depths. A slow sinus wave with a large amplitude on modulator six would light up three LEDs in column six, altering in a quite blocky sinus wave form. So this feature is very useful visualizing what your modulators do. It would be very nice to be able to use more than three LEDs vertically to display the modulator output value, though. It would totaly add to the general sci-fi spaceship targeting computer feeling of the mb6582 :) By the way - the V2 modulators rock the house :-) Bye, Peter

Nice! Thx! Smash? This would be a typical low-value item, right :frantics: ?

Welcome to the forum ;-) Good idea - i did this (excluding the ethernet part, which is still missing) on veroboard, but a pcb is always better. It would be cool, if you could create a small-size PCB, such as the IIC MIDI PCB, which also allows for installation in "crowded" cases. Edit: "small" meaning only as wide as necessary to just contain the ethernet port and the sd card slot. Bye, Peter

yo, pls correct my number from 30 to 50 (black transparent) - thx a lot :)

Hi, that´s exactly the one I used :-) Have a look in the for the wiring schematics :-) Bye, Peter

phunk, if you do it, please make mine 50 black/transparent instead of 30 - just had a new idea for a new project in 2013, that is if earth still exists then... :)
