I just received the Boss DR-110, a.k.a electronic toy. Very good packaging, condition looked as on the eBay pictures. Serial number 400300. However, when I started playing with it I noticed that only the HAND CLAP had any volume. The other sounds were there, but very quiet.
I posted on the 99musik forum. I shortly got an answer from a guy that never had used a DR-110, but had taken a look at the schematics. He suspected the balance knob, according to the schematics all voices are wired through the balance knob except for the hand clap that goes directly to the amplifier.
ALL OTHER VOICES -> BALANCE KNOB -> AMPLIFIER
HAND CLAP -> AMPLIFIER
I opened the DR, and guess what, the soldering on the balance knob didn’t look at all like the other ones. Note that the schematics are seen from the top, my photo is from the bottom, that’s why the knobs don’t make sense at the first look.
Just bought an Oberheim DMX. It was a real bargain, listed at 2000 Danish crowns ($350). I called him and offered him 2500 ($440) if he’d reserve it for me. He had one person that had contacted him before that wanted to buy it, and said he would call me if that person didn’t buy the DMX. At that point I told myself that it most certainly would be sold.
Later that day he called me and said that the buyer didn’t have the cash. So now I was first in line. I jumped in my car and drove to Denmark. Even if the condition wouldn’t be great, or if a voice card would be bad, it would still be a bargain. When I arrived and saw it in real life I couldn’t believe my eyes – it looked mint and worked flawlessly. I bought it for 2500. He told me that people after me in line had offered him 3000 ($530) and more. Very nice seller by the way! He told me that it’s this DMX that is used on this recording. I think the seller is the guy playing the bass in the video.
On the way back I turned on the radio and heard Into the Groove by Madonna. That must have been a sign. Just like when I heard Carrie by Europe when I was driving home with my JX-8P.
The sound is fantastic, very punchy. And extremely present! Already love it!
Now I have to stop writing and Google for MIDI-mods and check if the battery could cause problems.
In my studio I have lots of analog synths, but no analog drum machine. That changed tonight when I scored a Boss Dr-110 on eBay! I wouldn’t say no to a Roland TR-x0x, but since the prices have skyrocketed lately, the Dr-110 is a steal for $100. Have a look at the clip that persuaded me to buy it.
Must say that both machines sound fantastic, and very similar! One thing that scares me is the lack of MIDI, but the positive thing is that I really will have to learn how to program it!
I hope this one survives the trip from Canada over the Atlantic. Otherwise I can always call Dr Beat.
One really good feature is the possibility to chain two of these and get 16 I/O, shown to the computer as one device. Note that this works perfectly well with OS X, but on Windows, XP is the last version supported. NO 64-bit Vista / 7 / 8.
Connect the two devices with the Mac-lead (haven’t tried the 422 COM ports)
I just traded my M-Audio Venom for the Axiom Pro 49 from the same manifacturer. The reason why is simple – I need knobs and not a VA.
I won’t use the HyperControl mapping since it’s mostly for software instruments. What’s great is that the Axiom also transmits regular midi CC.
My first hands experience says that:
The keys feel very solid. They are visually piano style, but feels a bit lighter. The Venom had that cheap, light, plastic feel. Of all my keyboards, the Axiom keys remind me the most of the ones on the Kawai K3.
It has aftertouch – very nice! Aftertouch is something new to me, the JX-synths has it, but the aftertouch always dies on them. Doesn’t matter now when I have the Axiom as master keyboard.
It has A LOT of knobs and sliders – great success!
I’m actually not very interested in virtual analogs. With an all digital audio path you could as well use software instruments. One good feature though is that some of the oscillator waveforms are sampled from real classics. The Venom also has classic drum machine samples from 808, 909 and more. This review is quite nice:
Anyway, a couple of months ago I pickup a (not that) used Venom for about 1000 SEK / $150. My plan was to use it purely as a midi controller since it has four assignable knobs that sends midi CCs, so I thought why not.
After a few hours use, suddenly the A3-key started to squeak every time I pressed and released it. It’s hard to describe how utterly annoying that is, I was near reinstalling my Roland PC MKII that has been turned on and worked flawlessly for 17 years (and still going strong=quality) and sell or trade the Venom for a Behringer BCR-2000. Also, there was something lose in the Venom that rattled everytime I moved it.
With not too much too lose, I decided to try to fix the Venom. The first thing was to open the damn thing. When I looked underneath it, I was chocked to find 42 Philips screws! Insane! Not knowing which ones to unscrew to open the case, I googled for a service manual but couldn’t find one. This had to be done the hard way…
Luckily, it turned out that it wasn’t very complicated, but rather time consuming. What you have to do is simply unscrewing all the of the 32 screws that in “rectangular” holes. The 10 screws in round holes (marked by a red square) are holding the keys to the bottom part of the case. We’ll get to these later.
So I started to unscrew. After that, the top part could be lifted a couple of inches. The only thing left to completely detach the top from the bottom was this lead that connects the keyboard to the motherboard.
As soon as I opened the Venom, this little piece of glue fell out of it. This was also the piece that caused the rattling.
The next thing was to locate what made the key squeak. An interesting and quite confusing thing is that all white keys are marked E1 to E7, plus the C6 key that is marked E8. All black keys are marked C4.
You can also see the key spring. To remove the key, the spring must first be removed. Removing the spring is a no brainer, just lift the spring in the bottom or the top. As soon as I hade removed the spring from the squeaking key, the squeaking disappeared. I put the spring back and then the squeaking returned. I tried to swap the spring with one from another key, but that made no difference.
I figured I had to remove the squeaking key and one other key to compare them and see if there was any visible difference. The simplest way to remove a key is to push it towards you, the same direction as the arrow in the photo. It doesn’t take much force. Putting it back isn’t hard either.
Looking at visual differences, there wasn’t any, other than the low quality plastic stuff on the edges left there from manifacturing. You never see stuff like this in an old vintage Roland synth…
Next thing to try was to swap the squeaking key with another non-squeaking one. The bad boy was the A3, so I decided to swap it with the A5 key. To my surprise, the A3 stopped squeaking and so did the A5. Don’t ask me how, but this was the solution! I put the Venom back together, only using a third of the screws just to make sure that it still worked. Which it did! Case closed!
During my investigation I also removed the key circuit boards to see if the error was there. Looking back, this was totally unnecessary. I took some photos, so I thought I might as well post them here. Have a look at the gallery below.
When I got the Microwave it had a lot of german 90’s techno sounding presets strangely named like “Horny Bitch” and so on (Horny Bitch wasn’t even a brass patch = FAIL).
I had to get the factory presets back! Fortunately Waldorf supplies these on their homepage.
Go to the Sounds folder and download the midi version. In the zip you’ll find the factory presets and some bonus presets. To transfer them to the MW, simply open the midi file and run it in the sequencer. For me it worked directly, some settings might have to be set first, instructions are in the zip file.
My favorites so far are:
factory.mid – The factory banks
ppg/mwave2_3.mid – I think these are the factory patches from the PPG Wave 2.3
wavepool/digital.mid – A lot of lofi digital sounding patches, very PPG:ish
I just bought another Oberheim DPX-1 from a guy in Stockholm since the one I bought in the US arrived in a non working condition. This also has the 8-output and cd-rom expansion. I thought those were rare…
Another bonus is the sticker from “Music Mania” which was a music store where I bought my first synth/rompler, the Korg NS5R in 1996. I still have that one, but I don’t like any of its sounds anymore.
I was looking for a Waldorf Microwave 1, the one with analog filters. It was actually made in at least three versions; the Rev A, the Rev B and the limited edition “Mean green machine”. The Mean green machine was actually a limited batch of 99 Rev B painted green. To be honest, the Rev A is a lot better looking.
On the german eBay, a Mean green machine was up for grabs. Unfortunately I didn’t win the bidding and it was sold for €845, which is a real bargain. A so called steal.
The machine itself normally goes for at least €1000, but this auction also included an Access programmer. An Access programmer is for an MW what a PG-800 is for a Roland JX-synth. The Access programmer adds the hands on tweakability that’s missing on the Microwave, and they are quite rare and almost never sold separately. When they are, €500 are normal prices.
Too bad I lost the bidding, but I had to have a Microwave, so I got a normal Rev B with the latest OS.
