My Comments
Mike said he loved his D-5. I started to wonder what all the fuss was about. So after a little research I realized this synthesis method was brilliant! Basically they use small samples and mix them with analogue sound (or not, there are 13 different ways to add 2 sounds together). So I started keeping my eyes open for D-550's and D-110's. D-550's are still (at this time) around 500$ so when I found a D-110 for 40$ I decided I couldn't pass on it. With shipping it was just over 100$ and I still think it is a great buy. I mean c'mon I paid 100$ for my MKS-10!! So the day it arrived I was only able to take it for a test drive, but with my experience I could hear the potential. So the acoustic piano sounded like crap and many of the acoustic instruments are laughable. I imagine in 1988 these were still decent sounds, but I have to say i was a bit disappointed. Luckily I didn't stop there, when I got into the synthetic sounds that is where the magic happened. Even though these are factory sounds, they are quite good and imaginative. I really can't wait to try and program this thing. One thing I was surprized about was that the interface was quite foriegn. I assumed it would be similar to the U-20's interface, but I was quite wrong. I have skimmed the manual, so i have an idea of what is involved, now I will just have to spend some time with it. Oh and although it is multi-timberal, it's 32 voices can be used quick enough that the multi function, to me, is quite useless. For example a sound can use 4 partials so that is 4 WG's per note, so after 8 notes you will start to lose notes. And that is for 1 sound, there are 8 parts. You would have to limit each part to one note! When I have time I will be programming this to be mono timberal. I think this will be a great asset to my setup.
