SRX = 64MB? How? JV80s were only 8MB each!

[RobJuno]

I've been meaning to ask this for ages! How on earth are the SRX cards 64MB? Take for example the SRX-07 which includes:

All waves from... Total
JV80-04 Vintage Synth 8MB 8MB
JV80-08 Keyboards of 60s/70s 8MB 16MB
JV80-10 Bass & Drums 8MB 24MB

...Plus 'select' waves from JV80-09 Session, and JV80-03 Piano

...I doubt these select waves contribute more than the complete waveform list of the first three boards!

I have finally bought the SRX-07, but am not playing with it until a week's time... it will be my 30th birthday, and I'm being good and waiting til then to play with my new toy! (Proud of myself!)

I'm keeping my fingers crossed it's a worthwhile addition to the Juno-G, but now owning it has made me look again at the odd sum of its parts!

You forgot to add the guitar/bass waveforms from "Bass Legends" from Spectrasonics. There might be also some SRX-only waveforms (not previously seen on SR-JV cards).
I bet this is the case with other SRX boards too.

[RobJuno]

Apparently there are 860 waveforms on SRX-07.

255 come from vintage synth.
255 come from keyboards of 60s/70s
241 come from bass & drums ***All of which come from spectrasonics CDs themselves***

So far that's 751 waveforms from boards that claimed to be 8MB each. So there are 109 samples contributing a further 40MB? I'm very doubtful of this!

Guessing at the 'selected' waves from the piano and seession JV80 boards (instrument samples for which there are no instrument patches of that category on JV80-04/08/10), i'd say there are at least...
13 Piano
3 vibraphone
6 saxophone
6 trumpet/horns
3 flute
24 guitar
11 guitar noise

Leaving another 43 samples to find

Now I don't know if the 18 (RSS) samples will have come from JV80-04 or not. I think are special effect waves, and there is an RSS patch on the JV80-04. There are then 22 REV samples (which I assume to be reversed samples - copies of forward playing waves also on the board, and hence a rip-off to be considered additional waves!!!). Leaving only 3 samples to find.

I can't believe these 109 samples, that MUST include the piano, vibs, guitar, sax, brass, flute ROLAND waves can contribute 40MB!

So I still struggle to see how the SRX contains 64MB... UNLESS... the samples are the same source samples but of higher resolution.

Has Roland really got away with this all these years without anyone adding up 8 + 8 + 8 ≠ 64 !

no no no- they also add a very high quality sine wave to it. They don't list it on the waveform listings but I can tell you that it is there

[RobJuno]

???

Now I'm baffled!!!

So is this Sine wave accessible once installed?

What is its purpose? It wouldn't, by any chance, be used to add body to bass sounds, would it? In my opinion the Juno-G's internal bass samples are severely missing almost an octave's-worth of body and detail at the low end. Low-ish Es suddenly resonate, then everything thins out. And no, i'm quite sure it's not my monitors.

Final question... why should a Sine wave take up so much memory, either?

[Graeme]

maybe ...

(a) SRX cards waves take more space due to increased bit depth and/or sample rate?

(b) JV cards were 16MB, not 8MB?

(c) we're comparing compressed size to "equivalent" uncompressed size?

dunno

There's also a hidden Tetris game.

But there's a secret password to access it.

[RobJuno]

LOL. Now that would explain all the bugs in Roland gear... if it took the programmers 40MB to recreate Tetris on the Juno's LCD!

[madAhorn]

If you were making 64 meg expansion boards of different genre's would you make sure to fill all spaces or stop when you've completed the library of sounds desired?

I wonder if they "really mean" 64 meg board and not necessarily 64 megs or sounds...not that they say that...

Who knows, but it does seem some of the cards have a ton of sounds and some have fairly few. Sample size?

[cyclops]

It must be the same story as with the SRJV80 boards. There were some boards that included 255 waves, while others provided as much as 170 waves or so. And the SRJV80 boards were supposed to be 8MB boards. Each of them was packaged with a sticker that proudly read "Plus 8Mbytes".

[javaj_]

RobJuno- you do know I was joking- right????
Anyways- it is possible (and probable) that they re-compressed the original uncompressed samples to be higher quality for the XV engine.

Since I started this thread here, I'll tell you I intend to post my findings on the SRX-07 added to the Juno-G (in the Juno-G forum)
