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.

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.

Based on this schematic (pdf) for a voice-coil line out, I bought a Jensen JT-11-FL transformer and a 1590B enclosure to house it. This will provide the reference signal for the impulse response measurement. -- bradley

I use a David Clark 10S/DC headset, one of their Pro Audio series. DCs come with a noise attenuation chart (NRR dB).

I suppose one could use only rack-mount gear, modules, synths, VST players, etc. and run the whole thing with controllers via MIDI or Ethernet.

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.

At the expense of a more fiddly setup, two high-quality monitors on stands would give better audience projection than a KP408 on the floor, and probably better bass response. It would also give you the flexibility to adjust for different venues and different stage setups. Put them on the floor or on stands, spread apart or together splayed 60-90 degrees.

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, -- bradley

OMG! I like it better than the orginal. [video:youtube]

Perhaps next time, would there be any value in adding the dry sound of the clone as well as its internal Leslie sim? (c2d-dry_c2d-internal-sim_c2d-dry-into-vent)

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. I found this attenuation chart.

#4 had obvious tone generator bleed like my early 60's A100, only not as bad good. :wink:

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.

Scathing!

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.

To keep the cut straight, I've tightened a stainless hose clamp around the tube as a cutting guide.

I use this thing: Audio2000'S AST420Y-15 Short Speaker Stand. I think the legs might be 15" long, I mount two DXR10s atop at 90 degrees using a T-bar, though I wouldn't recommend it. It should be good with only one speaker on it though.

Tell him "no thanks", that your keyboards won't increase in value by being "relic'd". His guitars, on the other hand...

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.

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

It looks like the veneer is lifting (image 4 of 9).

I"d buy the TD-1KPX but it"s not available in the US. However, the TD-4KP has the same foldable rack. I may go with that and if drummer pleads, get a used mesh head snare pad.
