I have put the fan on the 5V rail, much more quiet. What method would be used to gauge if the 5V rail is overloaded now with the fan on it?? I don't want any parts to be stressed.

I know this is not the best way to describe a topic like this, but I have found several instances of graphical corruption on my V3 seq (that never used to happen on V2 on the same hardware). Its always been when going from a menu page to another menu page, some of the text from a previous page will land up transposed one way or another "over" the actual menu page. Going into edit mode will clear the corruptions. I have no method of reliable reproduction but I have seen it 5-6 times now and will try to replicate and document next time it happens. Its not a really bad functional problem, just doesn't feel as nice as it could.

That beast is HOT! I have the same blue lcd in my V1 SID, very nice... You can buy them at crest technologies stryd_one. I think they are about $65 but dont quote me on the price.

Thanks guys, got it happening. I did the bridge on the LCD (dont know why I thought it was a PLED!) but it didnt work. Took it off and put it on the board and it works perfect. The screen looks great! That's me sorted for the base board other than the fan issue, on to the CS now.

Hi All, Its on in the pic above where it is connected up to a different board (a normal single sid) for testing, same cable etc. I have bridged pins 9 and 12 on the actual PLED itself and it had no effect. I will try to bridge them under the header on the board tonight, but I cant imagine how that would make a difference compared to jumpering them on the PLED. Im wondering if there might be a different problem lurking? I connected up the PLED using the LCD guide in the wiki as reference. Cheers

Would the speed control eliminate the noise coming out the audio jacks? Im very partial to this red illuminating fan, dont want to give it up :) At the same time I don't want any unwanted noise.

Thanks wilba. I guess I must have done the wrong thing, I connected up pin 9 and 12 on the PLED but still no backlight. It comes on, but no red, no light. Have I mistaken what is required? Cheers

Has anyone had any backlight problems with the PLED's? My screen works with the backlight when plugged into another older single SID I have set up, but when plugged into the 6582 board the text comes up, but the backlight does not work (doesnt look very red either). Im afraid to just swap the polarity as it works with the other SID.. Any thoughts?

Here are some progress photos. Thanks to wilba's detailed documentation it has been very straight forward so far.

I have connected it using J25. Im having a bit of a problem in that the fan is very loud. I am thinking of adding a little speed control board with a resistor and a trim pot. Im thinking a 5W 100ohm resistor and a 10k trimpot inline with the positive signal. I have done a little test and it drops the noise by a huge amount (and you can tune the amount you can handle with the trim pot). The fan I am using is the fluro red ace 44w fan. I guess I could use the J3 connection, but I think I like the idea of setting the fan how I want it to run speed (noise) wise. Incidentally, are people having this as an extraction fan or intake fan? Im running with extraction unless its not the best idea...

If you did you might want to "transpose" them to other cc numbers so that they never happened at the same time else you will glitch your synths out (maybe desired??). Would be nice to be able to delay sysex too... Im thinking of a situation where Im using my Yamaha TX81Z (or any other FM synth needing sysex control) and to be able to delay the notes as an echo, but to send some to other channels (in performance mode with other voices happening) and then to finally delay some sysex to control the cutoff freq in a tempo sync manner. The possibilities are endless with this thing. Its quite simple as is, but im sure it could be dressed up a lot, especially with the developments in ram on the chips since its invention.....

I think I would have a better chance of walking on water ;) What about on a seperate core(s)?

Strangely with my TR-606 it will sync to the sequencer but only when the TR-606 is set to sync out. Very weird! It does sync perfectly but the 606 does not behave as per usual. Ive only really noticed this behavior since I went to V3. Is it possible I have wired it up back to front or something???

Thats a nice panel layout, would also be good to include holes for 2 panel mount LED's for an LTC module so you can see the in/out as well as have a thru. I think it would be good to have a few (or 4)of these in one rack with some sort of routing if they were not in the SEQ itself (which would me more handy as maybe the mixer layouts could include some saved delay configs and it could run from the master clock and benifit from the divider settings in the seq?). I have been finding that you can get interesting results having the input of the seq have the delay in it for recording from a master keyboard, then placing it over one of the IIC outputs afterwards to split out over some different channels with a different kind of delay. Having it realtime record the input with the delay can make for some interesting patterns. I wonder if it would fit into the sequencers firmware and agree with the concepts of the firmware if someone actually had the time to do the programming?

From what I can tell, its just notes in this one. I would like to see cc's happen! That would be interesting, might be a big mess but would be fun to try. I would love to see this become an option for the MB Seq on each channel.

The current firmware does not seem to do this, you can manually select the BPM but nothing more in terms of the sync. Perhaps someone could develop this?

Hi Ultra, Thought you might be interested to know mine is working 100%, its well worth building. I have it hooked up with the Midibox sequencer driving a Yamaha TX81Z in the attached example, there is also some drums and an undelayed sid. Cheers, John BMHP Midi Delay Example DCE Records LQ.mp3 BMHP Midi Delay Example DCE Records LQ.mp3

Its 9mb so cant attach it sorry! Try this one.... http://flavourfrenzy.com.au/mbhp.mp3 Having something playing up with the dynamic dns. Stryd, ive just rocked up in your home turf for the week :)

Oh no! Could you see it Stryd? If not can you see the web site http://www.dcerecords.dnsalias.com? Its on a semi reliable server... Is there a midibox file server I could pass it over to?

Its pretty awesome to be able to use mostly midibox gear and be able to create music while driving classic drum machines, do some external gear filtering etc... Only had to use the pc for recording and a few little edits. Nearly meeting my goal of not having the computer involved at all! Anyone planning on making a midibox driven recording device one day? To SD cards or somthing?? I can dream ;D
