Compact flash card to increase sample time and size

Compact flash card to increase sample time and size

Dear V-tribers,

I recently came across the Roland SP-606 NAMM video where the rep said that this unit can use 512 Mb CF card to expand sample time from 5 minutes (default) to 193 minutes. He also stated that this is the only product at the moment that offers direct off-the-card playback.

The question that could be of interest to the members of the V-tribe is whether it is possible to utilize the PC card slot on the V-synth and the VariOS module for the same purposes. Perhaps it could be achieved with a some sort of update?

Memory expansion would allow loading more and longer high quality samples or even complete tracks to the V-synth/VariOS. This would be useful in many applications including creating arrangements, sound sculpturing, and live gigs. Imagine that your audio arrangement is too high for your vocalist or the movie soundtrack is 5 seconds too long. Just load it onto the instrument and solve the problem. Have a complete sonic material but just want to add some Variphrase or COSM effects? No problem. And so it goes.

This would be especially valuable for the VariOS module since it was initially marketed as an audio arrangement device. However with the current memory and sample time it can be only used for short commercials and jingles at best. A more realistic option is to create material and to mix it down in another audio production environment, which, I am sure, is not how it is meant to be.


PS. Oher suggestions how to increase sample time and size are welcome.

V-Synth streams samples from RAM, and this is mainly because the samples are VariPhrase-encoded and need to be loaded to obtain this special data in them. Yes, too bad the V-Synth doesn't allow you to expand RAM, but I never found 50 MB limiting (and it's a per-project limit only). As about editing whole tracks - well I don't think they made this synth with such purposes in mind, and also when it comes to ~5% changes in pitch or time, time stretching does it just fine.

It depends on the length of the samples, the style of music, and the way you use the instrument. For patches and short loops this is a plenty of space. But if you try to work with longer audio material at high resolution you quickly run out of time or memory. I had some creative ideas that could not be realized just because the material could not be loaded to start with.

Perhaps that is true. But wouldn’t you agree that this would be a fantastic improvement and maybe not hard to implement?

Also let’s remember about the users of VariOS. They are supposed to use the v-producer to create compositions. And for serious vocal arrangements you might need longer phrases than “Don’t you let me go babe(eeh)…” ;)

Besides, often the samples are not as playable as real instruments or synthesizer patches. So I would prefer recording them live and working with longer phrases.


>> ...when it comes to ~5% changes in pitch or time, time stretching does it just fine.

Yes, but then you have to slice your track, stretch the bits of it, and later glue it all back together in some other environment.

Isn't that the idea of the PC card slot? So you can save samples to a microdrive or something instead and play it back without the PC. I.e. sample playback from the PC-Card...

The CF card can be used to store and load multiple samples and projects. However the size of individual projects as well as the size and length of individual samples is limited. This is because samples have to be loaded to the internal memory before they can be played. The internal memory of the VariOS is 46 Mb. In terms of sample time this means 2.5 minutes stereo or five minutes mono.

Direct off the card playback is not possible on V-synth/VariOS. However, since there are Roland products in the market, that have this capability, a question arises whether it is possible to add this functionality to our instruments as well. Or maybe there is some other way to increase the sample time and size.
