From: Campbell.SV@Xerox.COM > ...I know this is gonna sound like a stupid question,but hey!!!, > stupidity is a virtue.What is *digital* about digital delays?? Larry, A digital delay is digital because it takes the analog input and runs it through a analog to digital converter. The sound is converted to numbers which can be duplicated time after time (echo) delayed for a while or copied and read back faster or slower (chorus, flanging etc.). Also a microprocessor can play tricks with the numbers to simulate different size rooms and reflective surfaces (singing in the shower). After the numbers have been tweaked then they are run back through a digital to analog converter and presto- new sounds. The advantage over spring reverbs is the flexibility and much broader range of effects possible. A spring reverb always just sounds like a spring reverb while a digital reverb can sound like a small club or a large concert hall. Remember when people used to have spring reverbs on their car radio and when you would turn it up all the way and drive on a bumpy road it would sound like people fighting with metal trash cans inside a refrigerator or am I just giving away my age? Spring reverbs are very reliable so the problem in your Fender is probably a tube or connection. Besides, spring reverbs are not dead. I just bought a brand new Peavey KB-100 keyboard amp and guess what kind of reverb it has inside? To test your amp for springs just turn up the reverb all the way and drop the amp from an altitude of one quarter of an inch. You will find out if you have springs or not. By the way, another type of mechanical reverb was the plate type. This was a plate of metal with transducers on each end. It gave a reverb sound that was less jangly than the spring type. Is this more than you wanted to know? Regards, Rick Campbell PS I have a question for the net people who have Yamaha synths. I am trying to decide between a DX-7 (smaller, no computer required to program, cartridges etc) verses a KX-88 and a TX-7 (good keyboard, use with new synth modules as they come out) Anybody have an opinion based on actual experience?

I saw an ad in the March issue of Keyboard for a Tx7 programmer that duplicates the control pad of a Dx7. The rrp was around $400. Anyone know anything more about this ? -- Sunil UUCP: ...{harvard, seismo, ut-sally, sri-iu, ihnp4!packard}!topaz!mohan ARPA: Mohan@RUTGERS

I have recently purchased a KX-88 and TX-7. Since I want to use this setup as a piano substitute as well as a synth, smaller keyboards just wouldn't do. I am quite happy with this setup, and I am glad I didn't go for a DX-7 or DX-5. However, an external computer is really necessary for any but the most trivial tweaking of the TX-7's performance parameters. The KX-88 will allow you to send any MIDI command <= 20 bytes of data, but it requires entering in each byte as hex. A typical parameter change is about 8 bytes of data, as I recall. Alternately, you can assign a slider to vary the value of any given MIDI parameter. The KX-88 is tailored to to Yamaha's system exclusive data, but there are two "universal" parameters as well as the data dump of up to 20 bytes of anything. The KX-88 is VERY flexible, allowing the use of any slider, foot controller, breath controller, etc. to vary just about anything MIDI parameter you want. Without a computer (or DX-7), you can't even re-group the different sounds written out as groups to tape. Fortunately, I have friends with DX-7's that have allowed me to get set up well enough for now without a computer. I am contemplating the purchase of a MIDI computer (probably an AMIGA) Real Soon Now to make my life easier. This setup is NOT readily moved! The KX-88 alone weighs 63 pounds. But if you want a great keyboard, with good sound, and can live without RAM cartridges or built-in editing capability, I think you'd like this combination. This of course is just my opinion, but that's what you asked for. Try and get familiar with both setups because what matters is what you like, and its alot of money to spend on the wrong thing!
