Therezin Posted November 28, 2008 Report Posted November 28, 2008 Chips and boards arrived safely today - Man, those are some small pins. Looks like it's time to practice my SMD technique on some old RAM... Quote
Just Phil Posted November 29, 2008 Report Posted November 29, 2008 put my name down for 1 on the next go... edit new total is 2 chips 1 board Quote
TK. Posted December 5, 2008 Author Report Posted December 5, 2008 I've still 8 GM5 chips in stock from people who haven't paid yet (4 weeks after first notification, 1 week after deadline...)So - this is your chance to get the remaining ones, the quantity doesn't matter - 1, 2, ... 8.I've also more than 100 small PCBs in stock - let me know if you are interested as well (the rest will be sold during the next bulk order).Just PM me the desired quantity - NOW! - first come, first serve!SOLD OUT!Best Regards, Thorsten.

janvanvolt Posted December 8, 2008 Report Posted December 8, 2008 TK: Many thanks for the GM5 ! I just finished the 2nd Unit (besides small problems initially on the +5v) and all is working now. Now it's time to look at the port extension (on protoboard).--jan Quote

yogi Posted January 28, 2009 Report Posted January 28, 2009 looks like a cool project. :D Just added 4 to the wiki pg. Quote
grnsky Posted January 31, 2009 Report Posted January 31, 2009 I'm also on this list. I'm assuming we will be contacted for paypal payment when the minimum is reached and this will communicate the address? Quote
gnups Posted February 1, 2009 Report Posted February 1, 2009 hi, i did just add one gm5 and one pcb :-) Quote
Skunk Posted February 1, 2009 Report Posted February 1, 2009 Hi,question to all: did anybody already test the part under full load on all MIDI channels at the same time? If yes, did it work properly? I have currently an issue with this GM5 in a customer specific equipment, and under some strange circumstances it hangs up from time to time -- communication on USB and also sometimes on the MIDI ports stops. Only Power-Down/Up solves it.Cheers,Skunk Quote
cyberheater Posted February 2, 2009 Report Posted February 2, 2009 Okay. I've requested 5 x GM5 + 5 x PCB's and I've updated the wiki.Thanks. Quote
TK. Posted February 2, 2009 Author Report Posted February 2, 2009 Hi Skunk,question to all: did anybody already test the part under full load on all MIDI channels at the same time?

I have currently an issue with this GM5 in a customer specific equipment, and under some strange circumstances it hangs up from time to time -- communication on USB and also sometimes on the MIDI ports stops. Only Power-Down/Up solves it.which computer, which operating system, which driver, which HW variant?I recently had similar issues on my Mac with one of my GM5 modules which is connected to a passive 4x1 USB hub. After some troubleshooting it turned out, that the power consumption on the hub was too high (e.g. a MBHP_CORE_STM32 module + a MBSEQ Frontpanel with backlit LCDs was connected as well).I solved this by using an active hub with dedicated power supply.The strange thing was: the MBHP_CORE_STM32 module was still working pretty stable - so it seems, that the Atmel chip is less tolerant against voltage drops, but I haven't checked this further (as I found a stable solution...)Best Regards, Thorsten.

nykwil Posted February 3, 2009 Report Posted February 3, 2009 4 chips 2 pcbs added to wiki. Thanks. Quote
Skunk Posted February 4, 2009 Report Posted February 4, 2009 Hi Thorsten,which computer? an AMD motherboard with 2.4GHz Athlon (don't know the supplier)which operating system? WinXP SP2which driver? Ploytek special, customer specificwhich HW variant? customer specific -- a special board connected via the GM5 to the motherboard and a second USB-to-Audio USB I/F with 480Mbit, also connected to the motherboard. If the 480MBit line fails, the 12MBit USB-to-MIDI line also fails sometimesIn the meantime we found one possible problem for the failure: groundbouncing. During the initialization of the USB controller on the motherboard, looking for devices, a groundbounce shuts the device recognition down (it looks like that, but this is not yet proven). There seems to be no means in the GM -- only reset.Cheers,Andreas Quote
humbucker Posted February 10, 2009 Report Posted February 10, 2009 well, this is a very nice project :) 2 chips + 2 pcbs added to wiki.Thanks. Quote
Gioxannes Posted February 15, 2009 Report Posted February 15, 2009 Hi Skunk,Your manufacturer is probably Dell. I have exactly the same problem. But only with the AMD Athlon board (as well with the 3800+ as the 5400+), not with the Intel (Also Dell).The USB freezes after intensive use. I think it's a heat problem, but have not looked more into it. Under normal use the USB is fine. Put it under load and it hangs.If it is still possible to order, I would like 2 Chips with 2 PCB's.Gioxannes. Quote
rosch Posted February 15, 2009 Report Posted February 15, 2009 If it is still possible to order, I would like 2 Chips with 2 PCB's.here's the link to the list:http://www.midibox.org/dokuwiki/tk_gm5_bulkorder Quote
TK. Posted February 20, 2009 Author Report Posted February 20, 2009 I ordered 250 GM5 chips yesterday.Best Regards, Thorsten. Quote
TK. Posted February 23, 2009 Author Report Posted February 23, 2009 Ploytec was well prepared - I already got the chips.PMs are sent outNote that currently there are at least 20 spare parts - first come, first serve!Best Regards, Thorsten. Quote
SLP Posted February 23, 2009 Report Posted February 23, 2009 This is so weird. You can get a MIDI-USB-Interface with 5 I/Os for just about 15€!I mean, search for MIDI-Interfaces at thomann for example and compare the prices.Can anybody tell me why that is like that? :P Quote
TK. Posted February 24, 2009 Author Report Posted February 24, 2009 I mean, search for MIDI-Interfaces at thomann for example and compare the prices....and compare it with the BlacklistMost low-cost interfaces provided by Thomann are working unreliable.Today you can buy an USB based Multi Purpose card reader for less than 5 EUR, but usable MIDI interfaces are still so expensive like 10 years before. However, seems that this is still a field where you can save money with DIY :)Best Regards, Thorsten. Quote
cyberheater Posted February 24, 2009 Report Posted February 24, 2009 Thanks TK.I've requested 3 GM5 and 3 PCB's. I've PM'd you the details. Quote
