229.0. "Info about CZ-101 RAM cartridge" by HOLST::HERDEG () Tue Jan 28 1986 20:26

I'm interested in getting a RAM cartridge for my CZ-101 to save more settings.
Do these have batteries or are they really EAROMs or do they only hold their
settings when they are plugged in?  Also, what does one cost and where in
the Boston area can they be bought?

Thanks for any answers you might be able to give.

	I've seen them list-priced at $39. They will hold 32 sounds, but only when used with a CZ-1000. With a CZ-101 you can only store 16 sounds, 'cause that's all the CZ-101 will let you address. The battery is one of those little lithium jobs and I thought it was supposed to last 5 years. They've (the cartridges) have only recently become generally available. len.

	Hmm. Sounds like the old "you get what you pay for" syndrome. The cartridges I use on my Roland Super Jupiter hold 128 sounds each and I have 5 of them. You can swap them with power on too because they have write-protect switches. Now you know what to get when you trade up. :-) Ted (I just couldn't help saying it)

	Thanks for the info. Re .-1: As a total musical novice, the CZ-101 offers an amazing price/performance ratio for playing with and connecting to my Macintosh. I think I got a lot more than what I paid for. Once I get some MIDI librarian software for the Mac, the size of the RAM cartridge won't matter anyway. Mark

	Mark - Please continue to post (or send MAIL to me) your experiences with the CZ-101 and your Mac. A friend of mine (with a Mac) just bought one and would certainly benefit from your learnings. Thanks, Karl p.s. 16 sounds on the 101 cartridge and 32 on the 1000? Hmmmm, the salesperson assured us that the ONLY difference between the two instruments was the size of the keys.

	I don't know if it's the -1000 or the -5000 that increases the capacity from 16 to 32 programs. If you look at the MIDI addresses for the CZ-101 preset, internal and cartridge patches, you will find they are allocated in groups of 16 with gaps of 16 between them. The additional programs in the bigger machine fit into the gaps. Incidentally, my CZ-101 cycles through these addresses with the programs it has, rather than ignoring them; i.e., MIDI program numbers 0 - 15 (decimal radix) access presets 1 - 16, 16 - 31 access presets 1 - 16, program numbers 32 - 47 and 48 - 63 access internals 1 - 16, and program numbers 64 - 79 and 80 - 95 access cartridge 1 - 16. This means that if you use a CZ-101 as a slave, your master keyboard has to be able to generate program numbers in the "upper half" (64 to 123 decimal) if you want to get at sounds stored in the cartridge. Another interesting thing I found out about the CZ-101 is that the envelope generators will take over 90 seconds to ramp up to full amplitude at a rate of 0! For very slow ramps the differences introduced by the keyboard follow (making higher pitches have shorter envelopes) can be dramatic. I wish every synth I owned had EGs like the CZs. len.
