[ANN] Vee One Suite 0.6.0 - A third official beta release!

by Rui Nuno Capela

Howdy, Once again, the 'Vee One Suite' of 'old-school' software instruments, featuring a 'gang of three' made of synthv1 [1] as a polyphonic synthesizer, samplv1 [2] a polyphonic sampler and drumkv1 [3] as a drum-kit sampler, are being released into the wild as in so called 'beta' phase. Changes for this one third beta release are as follows: - MIDI bank-select/program-changes is now supported, for patch, preset and/or instrument program control. - New Help/Configure dialog is introduced for editing the also new MIDI bank/programs interface and user preference options as well (new home of the old Help/Use native dialogs option). - Presets may now be specified by base name, as an alternative to the complete preset file-path on command line argument (re. stand-alone JACK client). - Fixed parameters A/B comparison swap. As usual, all made available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. The Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later.

Re: [LAU] Audio over WIFI

by Leonardo Gabrielli

Thanks Len for the useful feedback. > In such a case, it would not be possible to add a WIFI that went to AP > then snake then FOH mix then monitor as there would be close to 30ms. The > WIFI would have to be a dirrect input to the FOH mix. > > In reality of the 16ms latency I mentioned, 5.3ms are the A/D and 5.3ms are the D/A (48khz, 2 periods of 128 samples in JACK at both sides). The remainder approx. 5.3ms is buffering large enough to compensate for the jittery behavior of network delay. In other words a packet needs reasonably less than <5.3ms to fly from one end to the other. With an AP things are a bit more delicate for the only reason that the packet must fly twice, i.e. the transmitter must get access to the medium ASAP, and then the AP must get access to the medium ASAP to relay the packet to the recipient. And they must meet the deadline imposed by the receiver JACK cycle. Medium access with 802.11 is the biggest issue in my experience. However, with an AP it won't be 30ms, it will be much lower. Obviously a TDMA mechanism would be much more useful for the transmission rather than the 802.11 MAC, but improvements can be done. There is one AES paper from a guy in Finland who managed to send 8channel audio at 192khz in packets of about 50samples each, see http://www.aes.org/e-lib/browse.cfm?elib=16138 I will take a look again at the AES67 minimum requirements, I guess to reach them a lot to development must be done. Basically the A/D and D/A must be done with 2 ping-pong buffers of 32 samples at 48khz, and hope that the network access and transport can be carried on reliably in 1.8ms. Nothing you could do with a general purpose platform or OS at the moment, but a good challenge for the future years. Cheers, Leonardo

So 16ms might be well workable. > > Psychoacoustic tests (many of them from the CCRMA SoundWire team and others) shows that 21-25ms is acceptable to keep a steady tempo. Larger values make the performers slow down, very low values make them accelerate! AFAIK in musical instrument design the 10ms figure is taken as a threshold for your instrument response (e.g. keypress --> sound), but in performance the values can be higher as said. Your inputs are interesting, and yes, I think AES67 could be the first step towards integration. More soon... Leonardo

K2000 / Zip drives / Linux

by Iain Mott

Hi list, I have a Kurzweil K2000R synth and a scsi zip 100 drive. I'd like to be able to download files from the web and transfer to the synth. I found a USB Zip 100 drive available which I'd like to connect to my Linux PC so that I can transfer the disks across to the scsi drive on the K2000. The USB drive is here: http://produto.mercadolivre.com.br/MLB-621544980-zip-drive-iomega-zerado-co… Does anyone know if this will work? Will I have any trouble with this drive on Linux working with K2000 formatted disks? Thanks,

Re: [LAU] Audio over WIFI

by Leonardo Gabrielli

Just to bring the discussion back to its original topic, I see and know already that audio over 802.11 is always thought of as a geek thing when not an insanity, but at my institution we felt this as good challenge for engineering research and I've been working on that as part of my PhD studies in the last two years. Updates and material about the project are reported at our research group webpage http://a3lab.dii.univpm.it/research/wemust The project, called WeMUST, i.e. wireless music studio, was started to test current network technologies in a *studio*, but later we also addressed live stage usage and a concert was performed last summer on the sea. In that case we acquired signal with Debian-based ARM platforms (beagleboard xm) and sent it to special devices from Mikrotik through Ethernet. The Mikrotik devices have directional antennas and created 802.11a bridges from sea to land. The networking topology allowed for monitoring and the round-trip latency allowed by the system was 16ms at lowest (but could be reduced with a different HW choice). The musicians could synchronize well and all had the same latency, imposed by JACK, running on both the ARM and the PC mixing the signal on the land. To recap, my opinion is that 802.11 can be as good as any other wireless technology in providing music and compared to legacy analog techniques the quality is not compromised (unless the link is so bad that connection breaks/packets get lost). Of course the 802.11 family of protocols is mainly targeted at throughput and best effort delivery, this is why the audio community must demand for amendments that allow a robust audio link, instead of neglecting the opportunity and relegating wireless connectivity to a marketing feature (as it is up to know, just a gimmick for product brochures to boost sales, showing ultra-cool ipad apps for remote control and nothing more). With this I don't mean saying that we should replace affordable and reliable audio cables with ultra-expensive wireless stuff. My goal, as a researcher is to thrive into the technical and usability challenges of a technology so widespread nowadays, show what can be done and check from the industry or the potential users if there are new applications that are opened by wireless and most importantly networking. Networking is a key aspect, indeed, because a point-to-point link is not novel, but if wireless connectivity can provide integration of functionalities and devices at low extra cost, it is worth investigating, IMO, at least at the academic level. Cheers, Leonardo

Audio over WIFI

by Len Ovens

No I am not asking if audio over WIFI is a good idea :) But I thought some might be interested in this: https://www.kickstarter.com/projects/432967670/jack-the-wifi-guitar-cable I note that the actually latency as a number is not mentioned anywhere. There are this many times shorter than something else kinds of things, but not a number of ms from end to end. They suggest that they have "a total re-engineering of Wi-Fi to suit real time audio" yet at the same time they managed to "keep it compatible with existing devices meaning no changes to your PC or mobile device." BTW, Linux is not mentioned anywhere and neither is open (source or otherwise). However, I posted this because someone was asking about running a few more audio lines wirelessly and the common thought is that it can't be done with reasonable latency for monitoring. These people seem to think it can. They are talking compatible with a wide range of devices (android included) so the drivers are not being redone either. Auto-seeking low traffic wifi channels might be a part of it, but from what I have seen, scanning channels takes more time than anyone wants for a gap in audio. -- Len Ovens www.ovenwerks.net

new laptop configuration

by daniel gomez

Hello I am an Ubuntu 12.04 user in an 7yr old laptop. At this moment I urge a hardware improvement for my work which is: sound synthesis and processing controlled by external data via USB (kinect sensor and customa arduino based sensors) and WiFi (osc data). So i have to make an investment in a powerful laptop with the proper configuration for my needs which could be translated into: * very powerful processor for the dsp algorithms * 3+ usb ports (not hubs) so i can connect the external sensors and an external soundcard * a good wireless card that would not use any resources from the main processor * a video card that would not interfere with the main processor Although I think i know the basic needs, I can not name the manufacturers or models of the processor, board, video and wireless card that would make my system work the best. It would be of great help if you could help me choose these elements based on your positive experience on any of them and even more it would be great if you could recommend a specific commercial laptop that could have these features/elements already packed. Thanks for your help Daniel
