This is great news to us WS-ers I have the old WS-A/D, there's apparently some kind of sample handling difference with the WS-SR (it uses the same format as the 01/W) instead of the common WS/M-series format, will your unit handle conversion back and forth? I've heard that there's more PCM data to be had for the SR, but I haven't come across any yet.
I had this idea in the back of my mind for a couple of years now. I started off developing this about six years ago, on the "old" core8. In the beginning I tried to implement CF card access but somehow never got it to work properly. Along the way I buried the project and resurrected it a couple of times.
I do not own an SR, but I have a A/D and an EX. The SR is probably not a prime candidate for the SCE, as it has more sounds on board already. I do not have any documentation about its PCM sound format. I would suspect that it is rather the form factor of the cards that makes the difference. Back in the day this was probably necessary to accommodate more memory in the cards, as the original WS and M-series PCM cards "only" hold 512k of waveform data.
Also, I doubt that there is more PCM data for the 01/W series than for the M1. I've been collecting the M1 PCM cards, and there were quite a few of them published. Most of them (well, most of the waveforms stored on them) work with the WS. If there was a real demand for conversion (and documentation was available), this could be handled by software on a PC. You would then save the converted set of data to an SD card and have it read by the SCE.
This is like this mythical Zadok thingy (one was on the german Ebay just recently) but with modern storage instead of floppies. What's not to like?
Now if we could only have a way to transfer our own PCM data across to the WS... There was this windows software "[font=Arial, Verdana, Helvetica, sans-serif]PCM Card Workshop" for 01/W-type cards but the site where it used to be hosted is gone...
Yes, I saw that offer as well. BUT, it came without power supply and without the connecting cable to the WS. The latter is a problem, as the SAM1 uses a PCB card with some electronics buried under a block of resin as connector to the synth's PCM slot. I guess no one knows what is inside this but Zadok. I have one of those units myself, but I would not want to ruin mine trying to scrape the resin...
But of course, everybody with a SAM1 could create PCM banks that he could provide to those using a MIDIbox SCE. Maybe that is incentive to some. I always found it quite strange to know that I would probably be the only one who could use the banks I created on the SAM1.
In that sense, the SCE is very different from the SAM1: it cannot (yet?) be used to create PCM banks yourself, it can only make "backups" of existing cards. (Or, it can be attached to a SAM1 to read PCM data coming from there.) I guess I should sell my PCM cards now, before everybody owns an SCE
. I have a copy of the "PCM card workshop" somewhere on my hard drive. Just drop me a line if you are interested.
The SCE prototype you see in the video is based on the STM32 core. The next PCB proto will carry the LPCXPRESSO as a shield. The PCB design is basically ready, I just have to send it off to the "boardhouse" on the weekend. It's quite a complex board...
