You know, while i disagree with everything about state control of the internet or user tracking etc, once in a while a dickhead will pop up that just makes me wish we could actually just say "**** you then mate, you will never ever be able to download this FREE software that the developer has made for FREE, in his own time and generously shared for FREE"

Take your greedy bastard attitude and go pay for something.

My question was about the dev time of this project. Are we in the middle or there are few tweaks to add.

dev time is: 'kinda quite a long time, due to other commitments, but you'll get the occasional update if you keep an eye out for it, and if you miss the download, ranzee will probably re-host it'.

The problem here is that many people is not really aware of what involves ASM coding, google it and have a look, or try to decode the original firmware, and once you have a proper unassembled ARM code go and try to implement any modification.

A whole new MIDI stack was implemented by @ pajen without using the original source code (probably written in C# or any other high-level language), he decoded the firmware and obtained pure machine-level code and worked on it,this is not trivial for the 95% of us.
Seriously.

Others are asking for money for less advanced
custom firmwares such as Shaman ER1. (Great firmware but not as advanced as Peter's one)

I want to take the opportunity to thank Peter for all the time he is dedicating to this Volca firmware, it is not common to find this kind of person in the net and even less common doing it for free so we should be more grateful in this time where one want have anything on demand and fast.

Does Volca Sample send CC on MIDI Out when turning the knobs? (not when playing from sequencers?)
Would it be possible to add that feature? It would allow for external gear to record knob movement.

Next week I will receive a MIDI Solutions Quadra Thru V2 (1 MIDI input, 4 MIDI outputs). The plan is to connect this to my Akai XR20 (or Roland MC-101) and use the sequencer on that to drive a few of my other devices. This also includes the Korg Volca Beats and Korg Volca Sample.

Ideally it would be possible to let the Akai XR20 sequence the Korg Volca Beats on MIDI channel 10 (which already works), and the Korg Volca Sample on MIDI channel 11. There is also a third MIDI channel available on the Akai XR20 (freely assignable), which could be used for the Roland MC-101. But the Akai XR20 is mainly used for drum sequencing. This frees up two tracks on the Roland MC-101, creates the possibility to save many more patterns than on the Volca's, has a song mode (pattern chaining, 99 songs), and acts as a master clock signal for all other gear.

I have a question about this MIDI channel 11 that is used in the unofficial firmware. The Akai XR20 does not have the option to trigger all kinds of MIDI control messages. It will be mainly used for note triggering via MIDI channel 11. Is it then still possible to edit the sounds on the Korg Volca Sample and trigger those edited sounds via MIDI channel 11? Or will only the unedited samples be triggered via this channel? For example: a 16 step sequence with edited sounds will be created on the Korg Volca Sample, and afterwards this sequence will be ported over to the Akai XR20. However, I would still want to trigger the edited "sample kit" on the Korg Volca Sample. Has anybody tried something similar and what are your experiences?

in theory you could have a midimerge into the Sample, adding the control data that the XR20 can't send. (sounds a bit cumbersome. you'd really want the sequencing to be done by something that can generate and send those CC, all-in-one)

this is where the issue of disabling vSample reception channels matters. as far as i can see (?), it isn't possible to disable ch12...ch16 in a standard midi configuration. (i think) ch1...ch10 can be disabled.

with the beta v4/v5 (previous non-public test version), you could set up keyboard splits on ch11, with 1 or more keys for each part. ch12 and ch13 were then used, respectively, as SEL and SAMP modes.(more or less; the thinking has changed a little with the new menu.)

and in that situation - say, if you already had ch1...ch10 disabled, so you are taking up ch11, 12 & 13 - one might ideally (in an ideal world), want to be able to toggle on/off the ch12 & ch13 operation, leaving it only using up one midichannel, ie: ch11, when you want to run your main sequencer, and have the full midi bus available for other device channels.
maybe that's a bit 'OCD'. but that's generally how midi channels are approached. the Sample is unconventional, certainly in its original midi implementation. compared, say, to a multitimbral sound module, where you have the option to turn reception channels on/off, or re-assign the reception channel for each part.

this is a hurdle with the Sample, *imo* - although i'd add 'strictly speaking': because in practice, say with v4/v5, it was really good to have the 'splits channels' (11), and then skip to ch13, and be able to revoice on-the-fly, reselecting the sample to be played by hitting midinotes, with them all assigned 1-per-key across the keyboard.

the focus has changed with v6/v7, so now you have ch11 as 'special' channel, but no splits, and ch12...ch16 seem to act all the same, eg: 14,15,16 are being 'wasted'. (unless i've missed something here)

there ought to be some way of selecting which, of 12-16, will have that role, freeing up the others; so then, if you want to disable 1-10 as well, it is only using up 2 channels, 11 and whichever one of 12-16 you want.

or maybe, get it all down to one channel, and have a way of cycling the modes? could get messy while running the/any sequencer though.

I'm having an issue with my Beatstep Pro and Volca Sample with Pajen's firmware 7, and it's an issue I've never had when using the factory firmware, so I wonder if it's related to the pajen firmware.

When I trigger a sample by pressing the key on the KVS, the sample plays at the correct pitch (speed parameter). However, if I trigger this same sample from the BSP, the sample plays back as if the speed parameter is turned all the way down, and thus the sample is pitched way down (several octaves I'd imagine). Also, once I trigger a sample from the BSP, if I then go and press that same sample on the KVS, the sample remains pitched all the way down, even with my speed knob untouched and at 12 o'clock. As soon as I turn the speed knob, the sample corrects itself and plays back at the speed/pitch dictated by the speed knob on the KVS.

Is there anything in the firmware that might cause an external trigger device (in this case the BSP) to change the speed parameter of a sample on the Volca Sample? I don't use cc sends or anything like that, and I am currently not using any of the fancier aspects of the pajen firmware. This firmware is installed, but I'm basically just trying to use the Sample as "normal" mode, as if I have the factory firmware installed.

Any thoughts or advice is appreciated. Thanks

I re-installed the Korg factory firmware and the BSP triggers the KVS properly, without the down-pitching, so this does appear to be related to the pajen firmware. Any ideas on how I can use pajen's firmware without the speed parameter being changed?

Goto "note filter', set it to "t-v" so that it reacts to TRIG and VELO and not NOTE, on the parts you want to use.
