Rob papen's Blue: a truly versatile synthesizer

• Manufacturer's Description

The people behind Blue clearly believe that putting its producer's name on the box will help shift a few more units – this isn't just a virtual instrument, it's a Rob Papen virtual instrument.

It only really works if you know who on earth Papen is, but, as he was responsible for the mighty Albino synth, maybe he's got the right to crow a little bit. Installing Papen's latest creation doesn't present any problems. There's no challenge/response system here – all you need to do is type in a code and you're away.

Overview

On paper, Blue is a beast of a thing. Indeed, it comes packed with seemingly everything you could ever want in a synth.

There are six oscillators and three synthesis types (analogue, additive and spectral), a couple of multimode filters, nine envelopes, four multi-envelopes, three modulation sequencers, one step sequencer, two effects… and a partridge in a pear tree.

Blue certainly looks impressive at first glance, then, but are its multitude of features going to stretch your computer beyond breaking point?

Some users have already reported that Blue is a CPU hog, with one forum member claiming that the playing of a chord pushed his levels up to 84% on a P4 2GHz.

Well, we tried it on an old PIII 1GHz in Cubase and never got beyond about 70%, even with five notes of polyphony played on the lushest of pads and sequences.

Generally, it came in at around 40%. It's fair to say that Blue is more demanding than Albino – two or three times more, in fact. It did run more efficiently in Live on our iMac G5, where we got levels of 10-50% for our five notes of polyphony.

So, the message is that although Blue can be a hog, it very much depends on your system. Our experiments certainly raised more questions about Mac vs PC and Cubase vs Live than ever before, but let's not go there just now…

Multiple synthesis engines

Because of all its synthesis types, Blue is being sold as a 'cross-fusion' synth. All of these synthesis engines can be combined, so in theory it's possible to create pretty much any type of sound you like.

However, as Blue is being sold on the strength of Papen's sound design skills, let's run through the presets…

Blue has so many different sounds that it can be difficult to get your head around what it's good at. The waveform sequences initially stand out – probably because there are so many of them – but there are also some quite wonderful bass sounds.

These demonstrate the synth's 'analogue' capabilities – the lush strings and metallic pads, on the other hand, show off its FM side.

All of this means that Blue is quite a hard synth to sell and market. Because it does so much, you might feel that it lacks any particular strengths or character. (Maybe that's why they simply decided to put Papen's name on it – as an all-encompassing mark of quality.)

Though they're by no means poor, it could be argued that the presets don't quite make the most of the massive engine that sits behind them.
