250th PatchPierre Post
Whooohooo...
Okay, it might seem a bit unnecessary to write a celebratory blogpost every 50th post, but it does feel like another milestone again.
I am happy to say the blog is still going strong after a relatively bad year for me personally, and glad that working on new blog-posts kept/keeps me distracted from all the negativity surrounding that.
Thank you so much again for all the support and the positive feedback.
I would like to share a few PatchPierre numbers with you about the PatchPierre universe:
- PatchPierre blog will reach the 75.000 pageviews this month, in a little over 2½ year.
- an average of around 5.000 pageviews per month lately, and this number is still climbing.
- Almost 1.100 people follow PatchPierre on Twitter
- Patchpierre.Net welcomed visitors from 126 countries

Top 10 countries / Pageviews
- Also more than 10.000 people downloaded and installed my free PatchPierre Mobile - Nokia app
(more info at http://patchpierre.blogspot.nl/search/label/Apps)
- Almost 15.000 views of my YouTube videos at http://www.youtube.com/netpierretv (subscribe!)

Finding new topics is getting harder as i have already reviewed most of the Doepfer modules i own, but i hope i can keep the blog interesting enough in the future with a wider range of eurorack related posts.
Donations will keep PatchPierre ad-free

Thanks again for the support, regular posting returns this thursday with the start of a completely new Doepfer tutorial video series by Raul Pena!

Quick Tip X : The Warm Up
Good performances need a good preparation and a warm-up.
That does not only count for sports-prestations, but also for your (eurorack modular) analog synthesizer.
If you are looking for getting the best out of your Doepfer A-100, understand that you need to give your system at least 20 to 30 minutes to warm up.
If you don't give it that amount of time, the tuning can/will probably be (slightly) off.
To be clear, it's not a question of the "A-100" warming up, but of the modules installed.
In some cases, the warm-up period of a module is mentioned in the manual or on the web-page of the module in question.
Especially VCOs like A-110, A-111-1, A-111-5, A-143-4 need a warming-up to become stable and reliable.
If no warm-up period is mentioned the VCO is stable very soon (like the CEM3340-based A-111-1).
The PSU type (Doepfer power supply I or II) has no influence.
That does not only count for sports-prestations, but also for your (eurorack modular) analog synthesizer.

Synovatron CVGT1 Eurorack-to-Buchla Converter
If you want to control a Buchla modular synthesizer with your Eurorack (or your Eurorack with a Buchla!) you should know that Buchla uses a different Volts-per-octave ratio as the Eurorack synthesizers, that work on a standard 1 Volts/Oct.
Buchla's pitch CV scaling conforms to neither the common 1V-per-octave or Volt-per-Hz (Roland) standards.
Buchlas generally conform to 1.2V/Octave (100mV/semitone) but older systems have 2V/octave scaling e.g. 258.
Buchla's pitch CV scaling conforms to neither the common 1V-per-octave or Volt-per-Hz (Roland) standards.

The other voltages lie in standard regions.
Control voltages and timing pulses of the Buchla are +5V (signals with sustain) and +10V (transients only), and should be compatible with most other manufacturers' devices.
Besides that, Eurorack uses 3.5mm mini jack sockets and Buchla uses 4mm banana sockets.
Besides that, Eurorack uses 3.5mm mini jack sockets and Buchla uses 4mm banana sockets.
Synovatron's latest module is a Eurorack format Eurorack/Buchla translator called CVGT1.
It was launched a few months ago at the Brighton Modular Meet at the University of Sussex just outside Brighton UK.
It was launched a few months ago at the Brighton Modular Meet at the University of Sussex just outside Brighton UK.
The 8 HP wide module allows Eurorack and Buchla synths to interact with each other, as the name suggest it provides a CV and a Gate/Trigger interface.
The module is an active module; The CV amplifiers use precision 0.1% resistors to set the scaling plus very fine adjustment by trim pots to achieve even better accuracy.
Trim pots (on the board) can be adjusted for trigger widths between 0.5ms and 5ms.

Trim pots (on the board) can be adjusted for trigger widths between 0.5ms and 5ms.
Not only does it provide the correct format connectors (and adheres to the Buchla color code) but it also deals with the CV scaling and offsetting and the gate/trigger and timing pulse conversion required to allow control in both directions.
CVGT1 can also be used to adapt to other banana connector synths e.g. Serge or Bugbrand which have 1V/octave using the "1" scale position.

Watch the CVGT1 in action below (although it is hardly visible in the video, but i do like the soundscapes):

Tony (from Synovatron) mailed me today that he can't make them fast enough, and that he's just over half way through my pre-order waiting list.
He underestimated the demand, initially he only bought enough components, pcbs and front panels for 20 modules (big mistake).
He will be building another ten or so but have negotiated with a local company to build the rest for him.

RIP Joop Stokkermans

The Magic Of The ARP-Synthesizer (1970) Orchestra conducted by Bert Paige. |
Stokkermans was an extremely important contributor to Dutch TV music, radio music and commercials from the early 60s into the late 90s.
Although he is mainly known as a pianist, but he also had a great interest for synthesizers since they first appeared.
In 1970 he recorded a full album on the only working ARP available in Europe at the time, together with help from technician Roddy de Hillster who programmed most of the sounds.
The album contains re-arrangements of standards from classical Bach (Air) and Tchaikovsky (The Swan) compositions, re-arrangement from Bacherach, Paige and Becaud and some compositions of his own.
Together with a full orchestra conducted by Bert Paige this turned out to be a very interesting and maybe even groundbreaking album in Dutch synthesizer-music.
