    This? <snip>

     

    That one looks like concert footage.

     

    (summary) "The life of tenor saxophonist/composer/arranger/musicologist Jim Pepper traced through his music, and with interviews with family, fellow musicians, and Pepper himself. Pepper was pioneer in jazz/rock fusion, and later utilized Kaw, Creek and other Native American songs and rhythms for a new Native American/jazz fusion style."

     

    I searched and found the video on the website of Upstream Productions (original source). It's looks like it is also available on Amazon but I don't know what an "Interactive Video" is. :classic_wacko:

    Check out the movie Rumble, which is a documentary describing the contributions of the Native American people to our current musics.

     

    I mention Charley Patton in a post above, he was Native, the Blues would not have been the same without him. There is a bit on there about a woman jazz singer who was a huge influence for Frank Sinatra and Tony Bennett. 

    Robbie Roberston from The Band was Mohawk/Jewish descent, the album The Band by The Band is arguably the first Americana album, written by a Native Canadian. 

    Link Wray was Native, Rumble was the only instrumental banned from the radio by the "authorities", who claimed it could incite violence. 

    The band Redbone, from Fresno (my home town) were all Native and performed in Native regalia, they had a couple of hits including Come And Get Your Love. 

    There is more, lots more. 

     

    It's a fascinating movie, I highly recommend it. 

    Don't forget Native American saxophonist Jim Pepper (Witchi Tai To).  There is a documenatry film about him and his music called "Pepper's Pow Wow".  I got my copy from worldcat.org. It's very inspiring.

  3. The project is to measure a set of impulse responses for a Leslie speaker. I measured a set in the 90s using an HP 3562A Dynamic Signal Analyzer. Those impulses were used for a software simulation of what was essentially a close mic'ed Leslie. I now want to load a new set of impulses into the simulation captured using a standard stereo mic'ing technique for L & R. I am hoping it will give a more realistic Leslie-in-the-room presentation.
  4. Tricky business... psychoacoustics, phasing, polarity, reflections, frequency interfering patterns, too small a sweet spot. Brings one around to wanting high quality mono sample libraries once again. :laugh:
    Very tricky. What do you want your listening exprerience to be?

    • as an audience member sitting 15 ft from a GP?
    • as if I am sitting at the bench of a grand, keys in hand?
    • like a well recorded piano through great stereo speakers?
    • ?

    And yet, you are stuck with whatever the manufacturer decided to implement as the *best* presentation. I suspect it's a significant problem for epiano designers also.

  5. What is a high-quality way to record a loudspeaker voice coil voltage?

     

    I'm doing a project in which I will be using ARTA to measure the impulse response of a loudspeaker in different in different acoustic environments. The speaker will be driven with 20 W or less, probably by a class-D amplifier with non-grounded outputs. I'll be using the loudspeaker driving voltage for the reference signal. The plan is to use a Focusrite Scarlett 2i4 (gen 1) for both the amp source and mic' input, and record with cardiod and blumlein microphone techniques.

     

    • Is there a high-quality active or passive DI that can convert a non-grounded voice-coil signal to a balanced line livel?
    • Could I use a simple balanced attentuator, maybe 10 kohm, to tap the voice coil and drive and XLR input directly?
    • Can I rely the anti-aliasing filter of the recording device to filter any class-D out-of-band artifacts before the conversion process?

     

    TIA,

  6. I've been using a David Clark 10S/DC stereo headset for years. You won't find higher quality.

     

    Edit: DCs have a number of accessories. I use the ear seal comfort covers, though they do cut down the seal and thus isolation a bit. The eyeglass cushions are on order.

     

     

    Interesting choice that I have never heard off. Apparently these are designed for pilots? Tank you for bringing these to my attention.

    I bought them, I'm guessing the 90s? My day job was at Collins Avionics, (airplane radios). D/C pilot headphones were everywhere in the labs. The magazine advertisement for these showed a model/business executive sitting in his office at a big wood desk with one of those aluminum airplane models on it, eyes closed, hands folded across his lap, smiling while wearing is D/Cs and listening to some tunes. I think I paid $150.

     

    At the time, I was playing tenor in a blues band and needed the hearing protection. There was, what I suppose could be called a down side. I was using a personal monitor feed and the isolation was so good that I could run it at very low volume and hear everything clearly. As a result it was sort of isolating in another way - a lack of engagement with the music. (There could be other reasons for that too I suppose.)

     

    A couple of years ago I noticed a buzz on one side when playing very low bass notes. I sent them in and D/C replaced both drivers and the cord for free. Obviously, I am a sold on them. :cool:

     

    I found this attenuation chart.

  7. Next task on my list: how do I cope with the less bassy sound of the newly arrived Neo Vent 2, compared to the Mojo Sim⦠:-)

    Your additon of the Vent has the potential to improve your bass capability. It allows you to tap off the signal into the Vent and drive a bass amp with it directly. An easy way would be to run the Mojo in mono, send L to the Vent and R to a bass amp. Ideally you'd wanto put a low-pass filter in front of the bass amp to keep the Leslie horn signal out of it, though I'd probably start with tone controls at first. Otherwise, the Rolls SX21 is a small mono 24 dB/oct crossover with a variable crossover point, 50 Hz - 2.5 kHz.

  8. Koss Porta Pro. 45 USD. Unless you have a really small head, you'll probably need to clip out the little blue plastic thingy that defaults them into the ear-fatiguing-head-squeeze position. Don't use them for mixing but for casual listening or band practice where you want to hear the ambient sound, they do fine. Good bass response.
  9. Oh no! Truly sad news! It's a shame those great Palmetto albums are not available on 180g vinyl which is my preferred format these days. I dug how he kept on recording and did some very fly covers like "Trouble Man", "Freedom Jazz Dance", "Juju".

     

     

    Backtrack is the first tune in this live performance from 2013. It starts at about 2 minutes in:
