Roland SBF-325 Stereo Chorus Flanger

Note: links to listings are affiliate links for which the site may be compensated.

"The SBF has 5 modes appropriately named “Flanger I”, “Flanger II”, “Flanger III”, and a Chorus mode that is part-for-part the closest thing you can get to the famous Juno choruses.

It has cool front and back panel inputs for both channels, it has phase invert for both channels (to get some nice swirly action going) and a CV in to control the frequency of the pitch externally (great for Eurorack modular setups!). This external control is another of those unique and creative features that make this box rock.

Flanger I is summed mono and sounds great. Flanger II is the stereo flange and sounds better, and Flanger III is a cross-feed flanger that sounds even better. You can run one sound in/out in stereo, or run two separate in's to get two different output signals. It's like having two flangers or two choruses in one box."

Two pics of the inside below.

"Made out of laser-cut silver acrylic, it features a decidedly retro 8-bit font face on the front panel. The engravings have been painstakingly filled with nacré white paint (with an added touch of yellow for the logo). The front panel is gently slanted for increased comfort and ease of use. Flat-top LEDs (in yellow and amber) have been used for a perfect “flat” finish of the front panel, and rubberized knobs provide a very pleasant touch. The LCD is a double-FSTN, LED-backlit negative amber-on-black one. Everything has been made to ensure no eyestrain and perfect legibility of the controls in all lighting conditions.

This quick description should already be a cause for excessive salivation, but there’s more! :D

Inside this beauty lie four MOS 8580 and four MOS 6581, each carefully selected and paired for optimal stereo results and overall balance. It gives you the best of both worlds! All components are high quality (Alps tactile switches and rotary encoders, Neutrik plugs, Bourns resistors, ST and Microchip ICs, Kingbright LEDs, etc), and sourced from single batches for consistency. The BC547 output transistors are even NOS! A silent fan is used, derated from its original 12V to ca. 7V for added quietness. Last but not least: the unit runs out of a single (universal) 12V DC power supply.

The case features no other screws than the ones used to fasten the circuit boards, and these are mounted flush. The bottom casing has been welded with acetone, while the front panel is held tight by suitably snug notches. All bolted parts feature locking washers to ensure a tight fit that will not loosen in time.

This machine has been built with great care, and is meant to last. It’s the result of several months of work, from the designing, prototyping, components sourcing, testing and selection (in particular the SIDs, which were singled from a larger number of candidates). It’s been such an amount of work that I will not build another one, as such, this is a unique piece."

Musikmesse 2015 - Korg Volca Wood Stand - Holzstand für die Korg Volca Serie

Published on Apr 16, 2015 Matthias played

"This is a wooden stand especially for the Volca series. You can set it up alike shown in the video or next to each other. Really good manufactured stand out of wood in my opinion."

Breathless MIDI Controller for iPad

This one comes recommended from MATRIXSYNTH reader Brian Comnes:

"For sitting in the big chair, this is 99 cents worth of fun, try it with animoog...especially if you can get wireless audio out to your better speakers (I use AirPlay in my home cinema set up)

Ok it's not an easel, but some iOS synths can really wake you up, and it's $3999 cheaper"

iTunes: Breathless MIDI Controller - Vinicius Mello

"Breathless MIDI Controller is a new kind of musical instrument with a simple fingering system that uses three fingers of each hand, but that achieves a range of four octaves, from G2 to G6. The fingering is familiar to recorder, flute or sax players, the main difference is that octave change is done by moving the iPad forward. Another big difference is that you do not blow, but the lateral movement changes the expression (assignable to CC7, CC2, Breath Controller or Channel Pressure).

What's New in Version 1.2
- Virtual MIDI
- Automatically save settings on exit
- Fingering editor
- Panic and Legato buttons"
