Kurzweil 1000PX | The Proteus Killer?

Espen Kraft

"The legendary and extremely expensive Kurzweil K250 sported some truly spectacular sounds for its time. Fast forward to 1988 and Kurzweil decided to put many of these sounds into different expanders. The 1000PX is one of them.

I really like this module. Very usable and extremely well sampled sounds.

Not very easy to edit from the from the front panel, but I really have no desire to edit these sounds today. This is the module I'm more than happy to use as a preset module. Much more so than the Proteus.

The video footage is from the very west of Norway, the bay of Hoddevik, known for its awesome waves and a eldorado for surfers. The tide was very low this day so not anything spectacular in terms of surfing, but the scenery is stunning. Of course I shot all these clips myself.

Some of the clips are from Kråkenes fyr, another spectacular site, even furter west, right into the Atlantic ocean.

Many thanks to Anders Jensen for letting me use this for this video! :)"

"Never thought I'd pick up a Roland SH-101, but... I've loved it ever since hearing Squarepusher 'Theme from Ernest Borgnine' and well... it just worked out to get this.

Used Eventide Blackhole VST on top of it."

Quick Intro the History of Analog Synthesizers on Digituria & Their Upcoming Software Synth

Supporting member, Digituria wrote in to let us know of a blog post they put up on the history of analog synthesizers. They are also working on a new soft synth named MATRIX DUDE of all things. No affiliation with me or the site.

The following is some info on the upcoming synth. You can download a beta and try it for yourself on their website here.

Two wavetable analog emulation that reproduce the same harmonics as the classical Model-D square and triangle, while keeping the sharpness of a digital sawtooth. The inverse sawtooth and note-sync allows you to combine both oscillators to recreate a PWM.

The synth includes a faithful recreation of the 4 poles 24db "ladder" filter to carve the sound. In addition to the cutoff and resonance there's an extra "spacing" parameter to move the cutoff frequency between the stereo channels.

Sequential Circuits Prophet 5 Rev 3.1 SN 1579

via this auction

"This particular Pro 5 is a rev 3.1 Purchased from Rod Argents Keyboards(London) in 1980, this has been owned by a top pro and has obviously been looked after. There are expected dinks & dunks, wooden end cheeks have a few scars, but overall is in very good condition, especially the keys (see pix). Properly serviced in 2020, we can offer 3 months full guarantee on this classic instrument. Everything works 100%..... It is wholly original, s/n 1579. Kenton MIDI retrofitted, with expanded memory of 120 patches ( 3 banks of 40 via mini-toggle switch near wheels). Technically, it is now rev 3.3 spec. The 120 patches currently in the expanded memory are the best I have heard in a Pro 5, for a long time. Sizzling bass sounds, screaming unison lead lines, mellow strings/brass/organ/fat analogue and some silly-boy stuff, thanks to the clever polymod section..and there is a litter of kittens schnuk in....."
