  1. Thanks for a very good and interesting read! The modular (OKOK, the sequencer) can be controlled from Lemur, what's not to like?

    It might make it to the stage soon-ish :frantics:

    How many people can do that with their modular gear? Oh, it also comes with a wireless bridge :flowers:

  2. OKOK, was just trying to be nice (without being sarcastic for once) or something :D

    At first I didn't connect what it would be, I started dreaming it was Stroopwafels laced with Kush, then I realized what it was. No, I wasn't disappointed. Only amused at my preconceptions :hug:

  3. Crunches is where it's at for the abs! That and training your lower back area... Hmm, needs to hit that part more often... MMA and cross-fit is also good and fun :thumbsup: Hope you'll succeed, I need to drop kgs myself again... Bleurgh, that's what I get from living too well... or rather unwell.

  4. ...and I hate bling.

    Soon.

    Aww, I didn't mean it in a condescending way :console: If we wanted tacky, tasteless bling we'd be doing this with pink or purple (the horror!) LEDs and gold painted knobs plus panel. This is more like good bling of the impressive kind. If I was more eloquent I'd go get my Baudelaire on with a good quote: "Tout ce qui est beau et noble est le résultat de la raison et du calcul " All which is beautiful and noble is the result of reason and calculation.

    Cheers!

  5. Yay for more Shruthi/MIDIbox cross-pollination! Guys, what if one was to draw a simple panel for one board? This could be cloned times x for larger panels and maybe we could ask the kick-ass friendly mr fcd72 (Herr Daniels) himself if he's interested? He always make beautiful Shruthi, Anushri and Ambika plus Shruth XT cases for us builders :sorcerer:

    Cheers!

  6. Cool cool!

    I own a Roland XV-5080 which is a bit like like a JV-xx, only with more sounds. I hope it will be possible to define your way of editing patches/banks/rhythm sets. There's a great page that explains the somewhat convoluted hierarchy employed by the JV-90, most likely all JVs, XVs, Fantoms and "new Jupiters"/Integra etc. It would be interesting if it was possible to define text lists on the SD-card with default patch/wave/drumkit names for the various expansion boards since some of these synths address these cards depending on the slot the card is installed in. That way it would become possible to load sysex, change the destination card slot to fit your particular synth and upload it.

    I haven't looked, but I assume that there's a similar story for Yamaha Motifs, Korg Tritons, Kurzweils, Ensoniqs and E-mu boxes from the 90's onward. If someone was ambitious he or she could make a programmer for an MR-Rack, a Fantom-XR, a Motif-XS or... Well. Lots of work :frantics:

  7. There was a brief discussion about this over at the Shruthi place... Olivier mentioned that your naive "graphically nice" square wave - from your first "Arduino synth" would end up sounding like shit due to the very sharp transients as soon as you'd transpose it up a bit. Obviously you'd need to use bandwidth-limited syntesis as you'll reach higher octaves. Both the shit-sounding square and a BW-limited version were played and contrasted. The latter ended up looking more like such poor synths as the Minimoog, Arp 2600, Korg MS20, Roland system 100, Sh-101, TB-303, SH-x, Jupiters, Yamaha CS etc. But maybe our ears are deceiving us?

  8. Hmm, I was thinking of collecting the encoder needs in some bulk or two, depending on people's location. If it was up to me, I'd get all the encoderama for the EU/Switzerland/Norway/Russia etc in a big box if I was travelling stateside and it would accompany me home. It's my way of effing the customs idiocracy. Splitting and shipping would ensue. Or, those encoders were a manufacturer warranty repair. All of this is purely hypothetical of course.

    In Sweden the customs people usually don't care if the order is for some small sum of say 500SEK (60€). Unless you're extremely unlucky, they had the Monday blues or something. Then the bastards at the postal service want 100SEK for their trouble of collecting customs payment, plus the VAT and customs on the order amount... You feel immense pain if your 4 Lolcat T-shirts costing 60USD-ish somhow got intercepted. Add 100SEK plus another 150-170-ish SEK customs and it all gets way more expensive :angry:

    Anywho, I guess we could find some interesting solution. Like ordering a boatload of encoders straight from the manufacturer in China using Alibaba if there's a good amount of interest.

  9. Hey jojjelito, I started a thread at Mutable since I couldn't find your post, though I did see it. Would love to see this get to over a 100 pcbs for another price break.

    Also, think we should consider a bulk order from Mouser or otherwise US side for encoders to get a big price break. Regular breaks are around 10,25,50,100 pieces and the price can drop significantly in those numbers.

    Also started a thread at monome.org to advertise this.

    Cool beans!

    My thread over at Mutable was titled MIDI Controller Building Blocks or something cryptical like that. I didn't feel like spamming the MI forum with blatant MIDIbox advertising, nor do I want to spam MIDIbox with too much talk of Shruthis, Ambika and Anushri or MIDIpal :whistle: It would save us all heaps of dough if it came to be a 100-board order, plus an encoder bulk would be nice. 4 boards, that's lots of switched encoders just for me... Add some more people and we'll quickly enter price nirvana! :frantics:

    I think that Jérôme has enough work with one bulk, hopefully someone in continental Europe (us Swedes would run into expensive postage to most anybody else) will step up. Or someone stateside who'd be willing to send a few boxes of 10USD worth of electronics...

  10. Hi,

    I tried to add myself on the list in the wiki page, but was not able to do so.

    The file is locked...

    Hi!

    Sorry if I sounded harsh - I just wanted to save Jérôme some work. Before you can edit the Wiki you need to register yourself there. It's a separate system from the forum, so registration is double... Anyway, scroll all the way down and press Login. Now you can press the Register link and get that done. Then, after logging in you can easily have your way with the list (and other pages) on the Wiki. Or, someone else is having a twirl with the Wiki page so try later...

    Cheers!

  11. Hi,

    Can you put me up for two?

    I will find proper user for them, I'm sure!

    Regards,

    René

    Peeps, help our esteemed PCB creator out by adding yourselves to the Wiki list mentioned in the first post, plus make sure that you have a proper registration on this forum as well! The registration for the Wiki is different than that of this forum, help creating traceability!

    Yes, the emphasis is mine, as is the quoted text.

  12. Peeps, help our esteemed PCB creator out by adding yourselves to the Wiki list mentioned in the first post, plus make sure that you have a proper registration on this forum as well! The registration for the Wiki is different than that of this forum, help creating traceability!

    Also, if you're new here, got few posts etc it might be a good thing to introduce yourself in a relevant thread or say hi to establish some level of trust thumbsup.png

    Not bad, the number of PCBs already exceeds 50!

  13. I advertised this slightly over at Mutable Instruments. With some luck there will be more people who are brave enough to also tackle the more DIY/Programming approach of MIDIbox :thumbsup: Also, it could give us cheaper boards (I always have ulterior motives and plans within plans within plans). That big, wrinkled space emperor dude got nothing on me :devil:

    First GM5:s, then they'll emerge better and more confident...

  14. Err, true. Level shifting is a fine tactic, but there's no way you can level shift beyond what you can feed your opamps with. One way of doing it would be to have a +-6V PSU, plus use a step-up regulator to get the 10-12V needed for the opamps positive supply.

    Or, no inductor dirty tricks, no switchers, just make a proper +-12V or +-15V PSU and feed your final stage opamps that. You can get away with something very close to -5V to +10V PSU if you use rail-to-rail amplifiers. But, that means accepting another constraint versus the same complexity for the bi-polar PSU.

    Confused yet? There is a third choice: +12V unipolar DC supply, plus a LT1054 inverter feeding a7905. The positive power is already present, but it can be stabilized using a standard 7810. This can feed a R2R amp -5V to +10V from a normal wall wart. However,the 1054 costs approx 3.50-4.50Eur or about 3.70Usd, depending on where you buy it...
