Hi Thorsten, Thats great, thanks! I will make sure that the new owner is fully aware of this and is able to get this MB Seq up and running. It has never been powered up so hopefully the proceedure will be reasonably straightforward. Keep up the good work! Best regards, Allan

Hi Thorsten, Many thanks for the fast reply. I don't think I have the ability to test usb midi connection and update bootloader, I've been out of MB stuff and electronics for two years and wouldn't know where to start, all of this is just a distant memory to me now :-( Am I ok to sell it as is, obviously making the new owner aware that this needs to be done and debugging may be involved? best regards, Allan

I've had to give up all of my SDIY projects and have a whole bunch of MB parts to sell. I would really prefer to sell everything as one lot rather than split it up Consists of the following parts, all pcb's and parts kits were bought from smashtv 1 of MB Core R4D PCB 1 of MBHP OLP3 PCB 1 x MB SID R2 PCB Fully assembled 1 x Ultracore PCB Fully Assembled 4 x DIN R5 PCB's 3 x DOUT R5 PCB's 1 x MBHP AOUT NG 1 x Set of parts for AOUT NG Including DAC 1 x Pic18F4620 MIOS V1.9F 1 x Pic18F452 MIOS V1.9F 4 x Pic's for Ultracore 16 x 24LC512 4 x DIN R5 parts kits 3 x DOUT R5 Parts kits 1 x Green LCD 80x2 1 x NOS YMF262 and 2 of NOS YAC512 sound chip and dacs for MidiBoxFM Open to sensible offers for the whole lot. I'm in the UK but can also ship to Europe and US.

Hi TK and all, NOW SOLD Seeking permission to sell my nearly completed MB Seq V4, doesn't need many parts or much work to get it up and running. Built most of it a year or two ago and never got the time to complete it. Front panel is 19U rack format, beautifully made by Julian "the beast" Front panel pcb is by Wilba, It has all micro switches fitted, all encoders fitted, turned pin ic sockets fitted. MBHP Core STM32 R1 which I think was from smashtv, fully assembled. I bought this with the Arm STM32 pre soldered in place. Haven't powered it up or tested it but pretty sure it will work fine. Includes two options for LCD display Option 1 - two of 2 x 80 Optrex White transmissive lcd's, white letters on green background (Expensive! these cost GBP28 each) Option 2 - two of 2 x 80 standard green LCD displays Includes 16 of bicolour led's Includes 58 of black push buttons for micro switches Includes 16 of black knobs for encoders Includes one of large black encoder wheel with indent So, all of the knobs, buttons and switches are included to complete the front panel A few hours work and some ribbon cables and TTL IC's and it should be up and running Don't have any time for SDIY anymore so has to go :-(

NOW SOLD! Thanks :-)

Not sure if this should be in this section or the fleamarket but thought it better to seek permission before selling. Sadly I've had to give up electronics so these projects are surplus to requirements and unloved :-( Lots of parts to build an MB-6582, including the following (most of which are in the photo):- Mainboard and control surface pcb's (Both earlier version from Wilba) 8 of NOS SID 6582's, all bought from Wilba - all still in packaging and unopened 4 of PIC 18F4685 (0000 to 0003) From Smash TV 11 of 74HC595 8 of 24LC512 8 of 28 pin wide turned pin IC sockets Two options for LCD Panel, one blue and one green display 100 of 3mm white LED's Encoders, more than enough, with four or five spare Micro switches Front panel and rear panel, both from Schaffer Packtec Case, brand new Not much more needed to build a fully loaded MB6582 Prefer to sell all as one lot rather than split. Price 295 Euros plus shipping

Hi Patrick, Many thanks for the reply. I'd reached the same conclusion on midi merge, I'll probably cheat and use a Philip Rees one I have lying around. I had two Maxtrix 1000's up until a year ago - I sold them because there was no real time panel control; your controller has answered all of the shortcomings of the Matrix 1000 so I've started buying again, I just bought one on ebay three weeks ago and I'm on the lookout for a second unit now, as soon as I get the second one I'll test them both as suggested; 12 voice mode is the one I'd really like to get working, not so bothered about layered mode. I'm in the process of ordering up the components to build my own Chaos Matrix, hope to be starting in the next week or two, think I'll have to build mine into a 3U or 4U rack case as I'm really short on space. I'll share the panel design when I get it completed. Many thanks for this great project, looks like it really brings the Matrix 1000 alive! Allan

This is a great controller and I'm going to build one for my Matrix 1000 :-) Did you get any further with midi merge on the inputs? One question - I actually have 2 of Matrix 1000 synths connected together as detailed in the Matrix owners manual, so I can either have 12 voices or the two synths layered and detuned for a 6 voice 4 vco per voice monster synth!. Will this controller work with both synth modules at the same time in both of these modes or will it only control one of them?

That looks absolutely awesome :) Really nice work, I can appreciate the hours the have gone into building it but I'm sure its all been very worthwhile.

I'd certainly like one set of boards if you would consider doing a small pre production run, I'm happy to pay up front too.........

If you are only wanting to control VCF's and VCA's then the Aout_LC would be fine, however if you are controlling VCO's then zipper noise and resolution may be a problem. You could always run CV output through Doepfer slew module first with a fast slew setting and this would help. My choice would be the Aout _NG, nice quality dac and 8 cv outs (rather than 2cv outs on the Aout_LC), which means you could have independent control of 8 CV Voltages from the MB Sequencer - for example you could control VCO pitch, VCA level, VCF req and VCF resonance all at the same time and still have 4 CV outs spare. Just my 2cents worth 8) Allan

Many thanks for the fast reply Thorsten, I'll go with PIC18F4685 and get the parts ordered up now. Another MBFM will be added to the ranks soon :) Cheers, Allan

Does MBFM work ok with 18F4685 or am I better sticking with original 18F452? I intend building with full control surface and 8 bank sticks, guess there's no advantage in using 24LC512 rather than 24LC256? Thx in advance, Allan

That sounds good to me. I'd be happy to be a "bleeding edge prototyper" at $50 for pcb to get things moving (assuming I could have panel .fpd file too, don't fancy laying that out myself :o). Just need another 9 impatient builders now.............. 8)

I have to say that I think this is the most exciting development yet for the MidiBox sequencer, along with the Ultracore module and panel and case hardware this makes the MBSeq project available to a huge number of people with basic soldering and kit building skills. I would be building one anyhow, but the time I save would probably allow me to build an MB-6582 too and still leave plenty of time to spend actually learning and using them instead of building. The fact that the case and control panel could also be used with the MBSeq 4 makes it even more of a must have............. :) I've added my order to the 100+ already on the list, the only thing that worries me a little is the panel and case seem to be holding things up at the moment. Any chance of just a pcb for those that are able to source their own switches, knobs, led's, encoders and Schaeffer panel? Don't get me wrong, I'd MUCH prefer to buy panel, case and components but I'm just impatient to get building ;)
