but…in my old seq3.4-layout i have some quick access buttons implemented, like: Direction, Length, Groove and Mode…
is it possible to add these aswell in the v4 ?..can´t find them in the HW-configfile…
and my SD card is somehow not working as it should…it reads/writes within the MBSEQ, but when switching to Mass Storage, Windows installs a new device “STM SD blah…” and i see that in explorer, but when i click it, it says “not formatted” …i tried different cards with different formats FAT32 or FAT also tried in WINXP and WINDOWS 7…with no luck…
since i did layout and solder the board myself, it might be only a faulty connection…but why does it work when using it within the midibox?
btw. the schematics on ucapps for the sd-card labels the connector to the core as J1 …shouldn´t it be J16??
this is very strange…although i can write and load within the MBSEQ4 i´m still not able to get a working connecting with SD-Mass-Storage and windows…i also tried the usb_mass_storage_device_v1_1.zip with same results…the device shows up in explorer but windows pops up with a “volume not formatted”. when i try to access it, it says “invalid function” or in german “unzulässige funktion”…midi via USB is working and uploading code also…but sometimes looses connection in MIOS-Studio2…
is it possible that i fried the stm32 somehow in a minor way?
in some other schematics for the stm32 i saw they use sometimes different resistor values for the usb-datalines (22 Ohm instead of 27 Ohm) paired with some caps (47pf) to ground like shown here : example
is it worth trying these changes…dunno if it would help…maybe someone has a clue or can point me in the right direction…
