A couple of years ago I bought a pretty cheap Yamaha AN200. Although Virtual Analogues in general and Groveboxes in particular hasn't been my area of interest I couldn't resist it thinking that it could be fun for the kids at least. They had actually just started to show some interest in some of my drum machines and synths. The Grovebox however didn't catch their attention for more than a couple of hours as they were fiddlin around with the preset techno rhythms.
Since then it has mainly been standing around in a corner in the studio just getting some attention every now and then when I needed some thick polysynth sounds. Actually it does sound quite good, but being bit of an orthodox when it comes to synths and organs I can't get the right feeling with the multifeature knobs.
Last week however I dug it out to try and use it as a sequencer for my Doepfer MS404. Don't know why I haven't thought about it earlier but I came across the idea after using my Roland TR626 as sequencer for the MS404 on my track DSTS. Even I realized that the AN200, even though beeing bit of a technobox, would be wiser to use is a sequencer instead of the TR626. One of the drawbacks, as I see it, with these multipurpose boxes is that you have to walk through the manual to get anything out of it. I mean with the Yamaha CS5or the Boss DR55 you just turn the power on and you know what to do. Anyway I sat down with the manual to the AN200 in the sofa this Wednesday to try to get a grip of the realtime and step programming features and pretty soon it came up to me...
It works just like an analogue sequencer!!! AN ANALOGUE SEQUENCER!!! I have had it for more than two years and hadn't discovered that feature yet (actually I think this was the first time I payed any attention to the manual).
Ever since I saw the Doepfer MAQ16 sometime in the mid nineties I have been dreaming about having an analogue sequencer of my own. And in the last years with cheaper DIY kits and the DarkTime I have been pretty close to ordering one. But someway with two kids, two cars and a house there is always something with higher priority in the households budget.
But now I actually own one, or at least a machine that works just like one. In the eight step mode (12 and 16 is also available) it is pretty straightforward and as long as you use it on an external synth instead of the internal VA you don't need to mix up your filter or osc settings with the pitch or the gate. I made a short demo of how it works on my Youtube-channel and hope to get a new track out on SoundCloud with this set up soon.

Another Philicorda GM760
Today I picked my second Philicorda GM760 up. Got my first one a couple of month ago but not all features were working the way they should. It was mainly the percussion-function that I wanted do get in shape, but I haven't managed to fix it yet.
The new one were on the way to the dump and didn't have the power cord so I simply picked it up hoping to get some use of it. To my surprise everything seemed to be working just fine when I connected it and I really look forward to getting into it a little more this weekend. Might even be able to sort out the problems with the first one now that I have one with the functions in order.

Philips AG7500 combo organ / AG7600 tube amp
Today I dug out my oldest Philicorda from the corner of my studio. The AG7500 is one of Philips first organ models. Released in 1963 it's packed with tubes both in the oscillators and in the amplifier. The amp,which also holds the spring reverb, is a separate unit mounted under the organ in the wooden stand.
My AG7500 has found its place in the corner since it hasn't been working properly ever since I bought it a couple of years ago. But today I gave it a try do fix at least some of the issues on it. The organ was out of tune, the reverb wasn't working, several of the keys didn't trigger any sound and others didn't return after pressing it.
I started of with opening it up to see if I could at least tune it and get a little better response in the keys. Tuning it worked out right, but the other issues were a little harder. I didn't actually understand where the keys made contact or how I could adjust the response or the springs of the keys.
The AG7600 organ amplifier
The amplifier part with the spring reverb is an interesting piece in itself. It has a 5 pole DIN output and a 5 pole IEC input connector and I guess it could work quite well as amp for any kind of instrument. This means my next project with this little thing is to build a cable or modify the amp to make it possible to connect a 6,3 mm instrument output.
Since I couldn't get it running properly I wasn't able to make a sound demo of it, but you can find some nice clips by others on youtube.

Philips Philicorda GM 760
I bought my first Philicorda around 1995 and then traded it for a Fender Telecaster about a year later. Probably a good deal then but ever since that day I have been looking for a new one.
A couple of years ago I then finally got hold of a AG7500 via a friend at work. It didn't seem to be working. But after a little soldering on the cables I got it running. However not playable in a traditional way. This one still stands in a corner waiting to be looked over.
About a year ago I then found my second one, a GM751. This one could not be tested where I bought it but since the price was more than right I took the chance. It sounded terrible when I first connected it at home but after a few hours connected everything fell in place without even opening it. This has been running smoothly ever since and has become my favourite organ.
A couple of weeks before Christmas I went to pick up my third Philicorda organ. This time a GM760 it's a spinet model with two manuals and bass pedals. And I didn't have the opportunity to test this either at pick-up but since it was completely free it wasn't much to talk about.
When I connected it at home everything, apart from the bass pedals and the percussion (fast, slow repeat) sounds, seemed to be working. The organ has a really warm organ sound with a marvellous plate reverb that is also possible to use on for example drum machines, synths or guitars when you use the Philicorda as an amplifier for external instruments via the connectors on the back side.
I made a short sound demo on the parts of the organ that is actually working. First it's the clean sound then with vibrato and reverb added.
The problem with the repeat function didn't bother me to much until I saw this video where the repeat function is used (around 3 minutes into the clip) and I really loved the sound of it.
Therefore today I downloaded the service manual and opened it up to see if I could find some simple solution to the problem. I can tell you right away that my skills in electronics and in Dutch are about equal and it took me quite a few hours to get an idea of how things could be working in the Philicorda. The attempt to fix the percussive section was without any success. But I took some pictures of the cards, components and wires inside.
Compared to other organs there are plenty of space and pretty easy to get an overview of the things. Philips has also made several smart solutions with hinges and such that makes it quite easy to access backsides of the circuit boards, keyboards etc.
Here's some close-ups from the GM760.

What's it all about
This blogg will mainly be about what's hapening in my studio. About my new and old gear, vintage synths, drum machines and organs.
I guess I'll start of with going through my current gear which consists of some Boss drum machines, a couple of analog synths, some Casios, and way to many home organs from Philicorda to Electone.
From left to right: Casio CZ101, Farfisa Foyer, Yamaha Electone D65, Philicorda AG 7500, Yamaha CS5, Solina String Ensemble, Philicorda GM 751, GEM Rodeo 49, Roland TR626, Yamaha AN200, Casio FZ1.
