: I have a QS8, it's a good machine but I've got some remarks and questions..

: -There is a very nasty 60 Hz hum (at least at my synth) and I can't eliminate it's source.
: I've checked it on grounded and ungrounded powersockets and checked my wiring and i couldn't detect
: any error. I've shut down any possible interference sources like computer, stereo, other synths etc. but that didn't
: helped. The AUX has this hum less, and i can't detect it on the Headphone-exit.
: I wonder which is the cause of this hum. Is it that the main powersuply is too close to the audio-exits (om my other synth
: the audioconnectors are far away of the powersupply)
: Or is my grounding not too good, or is it just me.

: -Has anyone noticed that you can hear some of the internal sounds in a loop when you are going below the C0. I discovered it when
: I was looking for some low noises when i heard a similar loop as when my Ultrasound crashed, sounding all sounds in memory.

: -I had some adress-problems with the Alesis demo-midisongs and the sysex in the software\midifiles\alesis directrory on the CD.
: Then my Alesis locks up. Is this a common problem?

: -Also a personal opinion about several sounds:
: The piano-sounds are good, but why was the resonance-box also recorded, if i have more than one note at once, the resonance is very
: irritating and making the sound sound noisier.
: The extra noise in some of the sounds (e.g. Jazzhrmnc (pre2-29)) is noticable. Is this a sampling-problem or are these faults in the
: filter.

: Tanks.

Fred, It sounds like you might be inputting to an amp input that requires a different microvoltage, i.e. a home stereo amp CD or tape input requires a higher signal (200mv.I think) than the QS puts out. Musical instrument amps usually have the correct input if it is geared for keyboards or something similar (50-75mv.) I got the same hum that you're experiencing with both a Roland kybd and the QS8. Try someone else's amp or PA system.
Hope this helps. Paul
