Re: [CZsynth] Best backup battery solution for CZ-1000?

2016-07-12 by Caleb Garner

replying to both emails in here more or less:


- cool about the battery..  yea that diode makes me nervous.. no idea 
where that would go..


- yes changing batteries once a year isn't the worst thing to do.. i'll 
probably be ok with it once i get Unisyn installed with DP3.. so I can 
actually send / receive sysex patches from it..  this way patches get 
saved with songs and dump backups can be sent / pulled any time..  i 
have the cartridge with a fresh battery so that's safe..  and the 16 
internal could be restored literally as needed when doing a session..  
so there's that :)     I have midiquest11 which is great, but doesn't 
run on OS9..  So unisyn will have to do for most things.


- i get it.. it could be risky.. but then i have a number of pieces of 
gear that the engineers left off power switches.  ART is especially 
notorious for that..  I will probably do a few things but I'm going to 
trust things like wall warts to handle the power surge since they are 
outside the gear..   basically things i especially prize or are 
exceptionally old like my Mirage and Akai S612..  The casio will get the 
treatment since for now I'm not going to mess with diodes personally 
unless I can find someone locally to help out with it..  things like my 
fender quad reverb i don't turn on like that..  that's very very old and 
something i don't use all that often anyway..


- do have items with sketchy / close to breaking buttons on things..  
like my digitech RDS delay.. it works still but the "joint" it pivots on 
is wearing out and it's "this close" to popping out..  are most of my 
buttons ok?  yes..  but the article spoke to me about this because i 
could relate to his point.


- so yea i see enough high end pros doing it to not be too worried and 
in reality most of the stuff I have is not really very valuable.. so 
it's not like i have racks of Moogs and such..  but yea as i said a few 
gems (to me) I might give a little extra love too just for good karma..


- yea i always turn down the audio for my speakers / mixer to avoid any 
popping sounds.. that seems to do the trick to prevent anything from 
being hurt turning on/of


Thanks! :)
Caleb
