Hi key juice. I am now onto my 2nd ex5 cos the first one i got sickened me off a bit,but after a couple of weeks without it i realised i made a mistake selling it and bought another one.
It is a cracking synth but it has its drawbacks, mainly lack of processing power and midi timing delays when playing sequences and the scsi speed,or lack of it,

Although its fair to say, there are workarounds for some of these problems.

I know i will never get rid of mine,it is quite a deep machine and there is enough to keep you learning for a long time to come!

If you want to know more about its pros and cons check out the ex5 tech site i mentioned in the above reply to scooby. This is a great site for anything ex5 and some really good people involved with it.
hope this helps.
Mick.
