    Hey!

    So great to see this new Golf firmware. Installed right away and seems to boot ok, although I have yet to use it to see how it behaves.

    I am just finishing this monstrous project that is the 9090 analog (mostly) drums (A Roland 909 without a sequencer but with midi) when I noticed this Golf firmware. It seemed like the perfect match for the 9090.

    As soon as I finish it, I will be testing the Golf with the 9090.

    In the meantime, it would be great to hear opinions on wether this device match would work or not?

    Cheers

    O yeah, that looks like a match made in heaven! Just remember to set each of the Golf’s tracks to send on MIDI channel 10 (the 9090’s default receive channel). Please let me know how it goes – and do make a video for me to add to the “users” section ;^)

    So excited about this!

    I just finished most of the component soldering. Still waiting for the mains transformer so I can test and proceed with the insertion of all IC´s and sound checking.

    Next step is to start thinking about enclosures. I was thinking about a desktop layout for it, but with space for the sequencer (in this case the MB/w Golf FW) on top of it, so it would tend to be either a rack or a sloped enclosure with most pots on the top part leaving an empty surface below.

    I will try and update this thread with any and all advancements!

    That sound really exciting – a hybrid Groovesizer 9090 is going to be awesome!

    Got everything soldered up on the 9090 this weekend. Had to make a main out board out of perfboard, since I was missing it in my parts purchase order and I don´t like to have components soldered to the jacks directly.

    All I am missing now is to wire all the pots (31!) and board interconnects, then insert all IC´s in place.

    Still waiting for the mains transformer to test it tho.

    In the meantime, I have to decide on the enclosure so as to cut the pot cables to length.

    So the 9090 comes as a PCB set – source your own components? Keep us posted!

    The 9090 is sold as a PCB+Sample IC´s (I think it is cymbal like the TR-909) and pre-programmed PIC (for midi).

    There is a Group Buy organized every now and then that takes care of all the components and pots, and it was supposed to include the main out board, but alas it was missing, no huge deal in the end, but for somebody obsessive about the neatness of the build like me, it matters.

    Anyway, still have to make up my mind on the enclosure.

    By friday the main Transformer should be here so I will get a chance to test my soldering!

    Incidentally, is there a way to attach photos to posts?

    You can upload the image to a site like imgur.com and use the img button above to paste in the url (make sure to add the .jpg at the end). Like so:

    I have not forgotten about testing my groovesizer with the 9090.

    I have stumbled upon issues with my completed 9090 and so far a solution has eluded me.

    It is not uncommon for such a gargantuan project to have “birth pains” and thus I still keep my humors up.

    Hope to be able to solve it soon and then jam with the sequencing done by the Multiboard.

    Keep the faith! From what I can tell the 9090 is worth the birth pains.

    Got the 9090 working.

    The beast is alive!

    I still have to mount everything on the enclosure, and found out I wired all the pots the wrong way round. At least I was consistent!

    I will update as soon as I can box the beast and connect it to the Groovesizer MB Golf!

    Success! Let me know how it goes.
