thank you very much for your coment and help. my midibox sid is v1, i have the midibox 64 and the midibox sid inside the same box but they work separete, the interconection its via the sequencer, so the only thing i need is to send the "save" instruction via the sequencer and then request the edited patch to the librarian program, with this i will be more than happy. about the desing of the case, thx... i am thinking on help on something to this proyect , i made the front panel and print over a "plastic" strong and easy to drill material, if somebody is interested i can do it for them for only the price of the material and post, i have all the equipment to do it because i work on a printing company, i dont want in any way to make bussines with this, thanks you and this site now i have a couple of pieces of incredible gear and i follow the spirit of this, so if you think it can be a good idea please let me know. thx again
