hi, i'm interested.

would this be the metal case from here? http://vandaal-electronics.com/enclosures/

also, what would shipping to switzerland cost? does not have to be quick...

cheers

simply get a powerpack that you normally use to charge smartphones etc. connect via usb to the preenfm and you should be portable. i have no idea how long the battery will last though :-)

yes, that would be ok.

one question, when one would want to build this, without smd soldering experience, would you sell preassembled boards with the stm32's on and burned firmware for the stm32f1? or what is the plan?

I might sell 1-3 of the 5 units I'll build presuming everything works fine and I haven't made any mistakes but don't count on me for getting into manufacturing these units.

People are soldering SMD parts all the time, it's not an impossible task. These are actually easy to solder SMD packages.
My only goal is to make this SMD version work and then publish all the files and firmware modifications so anyone can build them (or even start selling pre-soldered kits if they want to) .

ok, well if this works out ok, count me in!

since a lot of cpu will be saved by the extra controller that handles encoder etc. 44.1khz seems doable...

yeah i could live with that :) with 8timbres, i have everything i could wish for...

so the question remains how and where one could implement that transpose/offset? i think the combo preset would be a better place then the sound preset, because one may want to use the same sound in different combos. otoh if it is easier to implement in the sound presets, than that is ok as well. might as well save two versions of the same sound with different offset/transpose settings. but i think xavier is hesitant to change the preset file structure, because it will "break" all existing patches. so it should be easier to do in the combo file..

well, with the 8timbres version of the firmware that feature is not so pressing to me, since i can have 8channels in each preset.
but let's assume we are on the 4timbres version...
for live performances i have a controller that can send on 8 channels, since i never use them all on one preset (and since the channels represent different modes of the controller) it would be nice to switch the channels with the combo-presets. that way i can send a program change to the preenfm and all is adjusted for the next song/part whatever. reaching down to the preenfm and adjusting in the menu is of course no option :-)

but more importantly now (with the 8timbres version) is actually the offset of midi notes to me. so that i can play treble parts and bass parts on the same controller. let's say i1 has a bass part and i2 has a melody part loaded. i can then play both on my controller but i cannot switch octaves on the controller so fast. if i could adjust an offset for i2 i would set it to +24 and all incoming midi on i2 would be 2 octaves higher.

these two features (midi channel and offset) are very common on many multitimbral synths, and are usually part of the combo/multi preset, hence my suggestions. i'm simply used to that workflow and the preenfm would integrate much smoother into my setup... :-)

thanks for taking the time

what about pressing the inst button and pressing an encoder down, or inst and menu?

ok fair enough. i get that. so there must be some other way  8)
i will think about it...

If you spot any kind of error in the schematic or in the placement please let me know in the following days.

i could not find a link to a schematic.

xavier,

with the recent activity in the firmware i think it would be a good time to implement the combo settings page after i4 (i8 respectively  ;) )

did you do any thinking in that direction? as i said before i think most crucial settings will be:
midi channel for each instrument
midi offset, transpose +-48 semitones all incoming midi on an instrument

find the 8timbres version of 2.08a in the 8timbres thread...

ok i massaged the 8timbre version and the latest 2.08a firmware together...pfffh. i have to learn to use gits merge i think. altough it said it could not merge automatically.

find attached the firmware. i also included my program change mod, that allows to specify what program change does change (combo, bank etc.) and i increased the maximum lfo frequency to 599.9 hz just for grinse. as xavier predicted, the display looks funny after 99.9 (it sputters into the bias number) but it appears to work fine.

cheers!

Great! Thank you Lokki.

And what about the glide ? Does it work ? Any tips on wich parameters give interesting results on the Preenfm to assign them as CC messages on the seaboard ?

you will have to set pitchbend accordingly, and it should work yes. and load the same preset on all four slots and set the voices to 1.
