Roland MC-505 Groovebox

An all in one techno music production studio, this machine has it all. A massive collection of professional and coveted electronic synth and drum sounds, effects, built-in real-time VCF and envelope knobs for tweaking, a sequencer/arranger, and many other great additions. This is the successor to the MC-303 and is now much more advanced. Its sounds will be familiar to any techno-head.
The LFO and resonant filters allow quick and easy sound manipulation. The new D-Beam allows you to randomly tweak your sounds by passing your hand over an infrared beam! It has a great sequencer for building your songs (with groove quantizing and part level faders for mixing) as well as many idea catchers like the phrase sampler and arpeggiator.
This is an all-in-one music machine that's great for DJ's or anybody else who wants to create slamming dance tracks. Designed as a stand alone machine, they do not work quite as well when incorporated into a multi-synth keyboard rig. It's perfect for beginners and advanced users, but offers the most possibility to those who will use it exclusively. By the way, in comparison to the MC-303, this is far better especially in the quality and quantity of sounds! It is used by Beck, Chicks On Speed, Peaches, Freddy Fresh, and Cibo Matto.

I boycotted buying Roland products for a while espescially on items another manufacturer might make also. Which in my book is a shame because I've been buying Roland ever since the SH1000.
So for me, 8/10 without accounting for the display issues, or 3/10 with display issues. (You need to see what you're doing when you're doing it - like the names etc.).
Very, very disapointed with Roland over this display issue.
I like this machine a lot for all the things it can do like Midi control over other synths, pattern sequencer real time control etc.
What I didn't like was that the display pixels went on it and Roland would not replace the display screen under some sort of 'hidden warrantee'. Which is a shame because it seems just about all the ones I've seen listed for sale have the same issue.
Since I use it as a 'band in the box' with my original patterns to play against, I needed that screen fixed. So at great expense to me, another screen was customized for my MC 505 by techs. It cost me just over $200 to get it repaired.
Part Two to follow...
the peak filter can produce some fun results.
Only a few waveforms are usable and drums are too
compressed.
Sequencer is overloaded after recording 2 knob movements.
So....my 505 is something like a toy I use once in a while........
The 505 uses the same synth engine as the JV-series. This means you get access to very powerful editing functions, which makes this groovebox more of a real synth compared to the MC-303.
All in all a very powerful music tool in the studio or on stage. And it's built like a tank!
The estimated value is a tad over the top. These machines go for around €400 ($570) on eBay.
