Multichannel analog I/O audio interface: experiences and tips

by Jeanette C.

Hey hey, my two old Delta 1010 cards are definitely dying now. So I need replacement for all those analog I/Os. I have found three candidates: Behringer X Air XR18, Presonus ARC16C and Tascam u16x08(?) and would be glad if anyone could share experiences with them under Linux. I'm also looking for further alternatives (see my minimum requirements below). I definitely need multichannel audio coming from the device. The Tascan appears to have many microphone inputs, which cannot serve for line level input, if that really is so, it's out. The Behringer requires the app, which I have not been able to test, but its accessibility is not that important, if the XR18 will remember settings across power cycles. The ARC16C's description reads very well, but there are many dubious reviews, perhaps it was an early "Monday" manufacturing problem though. My requirements: one mic in (no need for +48V phantom power), one instrument in (Clavinet, I think it needs extra amping), at least 12 line level ins, 14 preferred. Four outputs (main out and to "sends" to outboard). No DSP, routing/bussing,... My workflow is purely centred in the box, using JACK for all connections. Based on the three candidates, I'd say my price range has to go up to 700 EUR. Any experiences and further suggestions are very much appreciated!

USB Compliant MIDI

by Bob van der Poel

I'm looking at the Casio WK 6600 keyboard and see that the old fashioned MIDI connectors are replaced with a USB - B connector. Can anyone answer: 1. These connections are okay to connect my linux desktop computer to the keyboard using a standard USB A-B cable? 2. How long can the MIDI cable be? I suppose if it's too short I could always insert an extension cable? 3. Could I use a real MIDI cable from the computer and convert that to USB? Thanks! -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

temporary jackd in tmux window

by Mario Lang

Hi. This is just too cool to not share it immediately. For tmux users wanting to be able to peak at the output of their autostarted jackd, put this in ~/.jackdrc: /usr/bin/tmux new-window -d -n jackd "jackd --temporary -d alsa -P -p 264 -d hw:sofhdadsp; tmux wait-for -S jackd" ; wait-for jackd Whenever a client starts the server, it will run in a separate window. The wait-for is there to avoid returning immediately, which would confuse the client. -- CYa, ⡍⠁⠗⠊⠕

[music] New album and new track: dark Spiral

by Jeanette C.

Hey hey, I'd like to present my latest song: Dark Spiral: https://youtu.be/Y7pL-gVw38o A wild ride with lots of genre sghtings at the wayside: synth music, metal, prog and even a bit of classical inspired music. A polyphonic melody section with lovely analogue synths, a bass section heavily featuring Yoshimi and really punch metal-like drums. Not to mention the "spiral" of ecstasy, a key-modulation fest! This is also the last track of my latest album: Spiral Dreams, which marks a journey through Berlin School synth music, prog and deeper downbeat electro, by its natur relying on Yoshimi and Csound a lot: http://juliencoder.de/nama/spiral_dreams/index.html Enjoy and best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c You should take me as I am 'Cause I can promise you Baby, what you see is what you get <3 (Britney Spears)

Looking for portable stereo recording device

by Jeanette C.

Hey hey, I had a Zoom H4N for a long time, which is now broken. I know many - if not all - portable devices will register as class compliant mass storage devices, so Linux isn't such a specialty to consider. But I have other requirements and know that there are some people - occasionally - working with field recordings. Perhaps thinking out of the box may yield the best path. I really need a stereo microphone which can record to a memory chip as uncompressed - or lossless - 48kHz 16bit - or upwards. Since I'm blind the device has to be usable, i.e. no touchscreen and not too many/complex menus. The more static such menus the better. And it should definitely have less self-noise than the Zoom H4N. I'm looking for something up to about 230 EUR. What I've seen so far: Olympus ls-p1, it has a speech menu, less noise, but I hope that there's better quality around. I don't know about the usability of the ls-p4, nor about its sound improvement. I've seen the Zoom H5, which apparently has less noise and I can only assume is easy to use, once format and quality are set. I have considered a smart phone solution, but last time I tried, I couldn't mount my iphone app containers on Linux, so that approach I will take with caution. I think there are some microphones around which can record to a built in card/mememory... If it helps: I often used my recorder for field recordings outside, spontaneously stopping when I heard something interesting. I also used it to walk around in sonically interesting spaces. I have rarely used it mounted or set on a stable surface. I'd appreciate any pointers and suggestions.

Ambisonics IR-Reverb?

by Michael Jarosch

Hi! I want to make some recordings with my Røde NT-SF1 and add some mono sounds, later, which needs the same reverb to make it fit into the recording. I wonder if there is a reverb working with impulse response for ambsonics…? Greets! Mitsch
