44.1kHz...

I'm betting you will go with the 44.1kHz because it is a piano and will suffer greatly at 22.05kHz (but that is my guess). If the CP70 is an important Voice for you then worry not about it using up half the memory capacity of the FL1024M... consider it well used memory! If this is a "go to" Voice for you - then use the memory for it. But if it is something you only use once in a while then load it once in a while. But your Flash Board should be about VOICES you "have to have" - because they are ESSENTIAL... They are your "go to", "have to have it" set!

Just for perspective:
You have a van, it's 1977, and you have decide which keyboards you are going to bring to the gig. Are you packing up the Rhodes Suitcase73, the Wurlitzer, the B3, the CP70, the Clavinet, the MiniMoogD and the Arp Odyssey? What do you leave out to get the CS80 in there?

My suggestion - load the CP70, play it for awhile, if it is a keeper then keep it, if not DELETE it _ its 2016 you have that option! 🙂
But to load a lower fidelity version to save room, (for something you don't have yet) how do explain that to your audience!

44.1kHz is what the internal waveforms are sampled at? I would have guessed lower, given that the onboard memory is lower than the flash but I shall defer to your superior knowledge of things Mister Bad Mister 😉

I was surprised to see the Keyboard Waves CP70 set taking up 512Mb when the CP1 piano (free Yamaha download) has more waveforms and is only about 120Mb. Are the CP1 sounds likely to have been sampled at 44.1kHz too?

I like your "1977" analogy! Well the CP70 I always loved, back in the day when I played before (late 80s-through mid-90s) when I owned Yamaha synths and modules I always wanted that sound but Yamaha never seemed to include it in their synths.

I've heard the demos of the onboard CP70 sounds, but the Keyboard Waves CP70 set sounds truly awesome. A definite "have to have it" set of sounds.

I'm currently about to start playing again in a rock covers band that split up 18 years ago! We do a few U2 numbers where that sound is going to be used in anger (especially "New Year's Day"). Oh how I would have loved to had it before but now I can make up for it with MOXF + Keyboard Waves set.

I'll go with the 44.1kHz and use the 512Mb....just need to try and remember how to play keyboards now, having been away from all this for so long!

Well, thank you for that, I think (!?!)

Some libraries are inefficient in how the data is stored. It is common practice to sample the lowest loudest note first. And set the gate time according to that sample. All notes are then sampled with this length... it makes for an impressive sounding sized sample, but actually mostly it is empty space... Yamaha AWM2 is a method of efficiently sampling and storing the data to ROM. Some libraries try to impress with SIZE - when actually it is of little consequence. I've heard 3GB pianos that were out done by the Power Grand (which is 2.4MB) that's right 2.4 MegaBytes!!! Size is secondary, in sampling - it does not guarantee a quality recording, only that it is big.

Like some people buy the loudest speaker convincing themselves that loudness matters. Learn to just listen and not judge by SIZE of the sample data. Use your ears!

121MB (but who's counting) and yes, 44.1kHz

Just so you know: Electric Grand Library for MOXF

Thanks again Bad Mister!

Yes, I'd seen the CP80 library on the YamahaMusicSoft site. I might check that out at some point too 🙂

I guess being selective with which of the Keyboard Waves CP70 voices I decide to keep permanently on the MOXF8 will reduce the footprint on the FL1024M as the associated waveforms are what uses up the space.

Just before typing this, a courier arrived with a couple of YAMAHA boxes for me...:D

Well, you should mention, that only Yamaha libraries are able to use the proprietary compression algorithm which squeezes the samples down to 1:3 of its size compared to uncompressed PCM.

Unfortunally, this is not an option for third party developers. They have to use uncompressed PCM. So inefficiency is not only a matter of wasted sample space but also of being or not being able to use a more efficient storage format.

I guess, if you would give acces to the sample compression format that the MOXF and Motif XF is capable of, to the public, there would be much smaller and "more efficient in how the data is stored" third party libraries available 😉
