DESCRIPTION

This is a crude emulation of a tel ray variable delay device. It was built on the back of Michat's excellent tape echo emulation(s). I have left the multi-head function of Michat's space echo emulation in place, so this has more "heads" then a proper "tel ray", but that's just icing. There are tool tips and a handful of snapshots, if you have any questions, or suggestions for improvement, fire away.

Wondering what a Tel Ray Echo-ver-brato is? Check it out:

Credit where credit is due: This effect also features the EZfft Parametric EQ, Luca Capozzi's Tremolo macro, Jeff Brown's Push/Pull, the Toob Macro and probably other bibs and bobs from the UL (various authors). The great knobs are by Jonathan Style.

Also helpful was Piet Verbruggen and the Etap2/echotapper site - check it out:

1:43 AM, August 20, 2008 -->Last incremental update for the moment, I promise. This one is a big improvement on 2.1 though, honest.

10:45 AM, August 20, 2008 --> Version 2.3! NEVER SAY NEVER! Sorry, but here's version 2.6 (Thanks to NI's wonky upload form, should be 2.3), with another important improvement:

Version 2.6 adds:

- Made post-EQ LP filter visible(!)
- Reset LP filter point on all snaps, MUCH much better.

Version 2.2 adds:

- Revised (ahem, fixed) modulation eq section
- added fore/aft frequency analyzers (ripped from the UL) for the EQ to aid in making snaps. Turn them off to lower CPU usage.
- Revised GUI
- Revised Snaps

Version 2.1 adds:

- On/Off buttons for all "TelRay" effects in echo signal path: AM, EQ and PAN modulation
- Post FFT EQ LP Filter for further shaping of "reverse smile" curve, as a result the limited frequency response in the echo path is now quite pronounced
- Mod EQ settings tweaked (especially noticeable in the "Leslie"-like snaps
- Some internal signal path/structural changes
- Revised snapshots
- Revised GUI

Version 2 adds:

- Pan Modulation
- AM Modulation
- EQ Modulation
- Various Internal Tweaks
- Preamp Level Knob back where it should be on the front panel(!)
- Revised GUI (A and B)

Some Notes:

Use the "Tel Ray-ifier" knob to control the amount of AM/PAN and EQ modulation applied to the Echo Signal path...

Rate and Depth control the modulation of all parameters: Vibrato, pan, am, Eq mod etc.

Mode chooses configuration and activation of Echo heads.

Version 3

- Adds an alternate variable delay mechanism (swiped from the UL)
- Up control rate (in settings) to get rid of zipping/ripping audio from modulated filters

Version 3.1+
- New simplified signal path
- Replaced pan with Frequency Shifter macro by (c) 2003, Sean Costello / Valhalla Sound.

Gotta agree with Thomas Medes, this thing is frickin CLEAN. Turns keys into magic, even as of 2020.

Version 4.0 cuts alot of the dubious spaghetti wiring of the last version, replacing it with a more sensible signal path, and adds Sean Costello's excellent Frequency Shifter in place of the simple modulated pan used previously. Getting closer to the doppler/echo effect I'm after!

The Work-in-progress forum thread I cite above is dead, so I have uploaded the work-in-progress file as an update. Ugly GUI, but nice sound. Up your control rate for best results.

Yes, it's another incremental upgrade - but an important one, modified the post-eq LP filter settings, much better curves as a result - sounds good (better).

Kimmo - Twang/garage/farfisa/vox... you're speaking my language sir! I built this for my guitar (and yours too) as I've been wanting an *actual* tel ray oil can echo for a few years, but haven't had the disposable income⁄, so this was my economical alternative! I'm going to go plug Deep Space '68 into it... deep space lite is a macro? I was playing around with adding reverb/diffusion in the chain, but couldn't get it to behave.

I tried this with guitar. Very nice effect pack. Sound is very real. Good for 60´s twang/pop, psychedelia/garage guitar and Farfisa/Vox-like organ. I tried this with Deep Space 1968 too. Very Hendrix - and I did have no input at all! Would be cool to integrate "Deep space lite" into this.

Glad you like it Donovan - just a quick note, I'm working on a quick update based on some suggestions from Sowari - building in some options for effects activation and routing - also a mono/stereo output switch. I'm also toying with adding a LP filter to further shape the EQ curve on the echo signal (if I understand you correctly Piet!)

James Elliott, So I tinkered, and tinkered and tinkered, trying to come up with something I imagined would be like an organtone ... ahem ... without any point of reference, so please keep that in mind... anyway, this is what I came up with - version two, with am and pan modulation... you can get some pseudo-leslie-like effects, give it a spin (har har) and let me know what you think - suggestions and corrections are always welcome, and hey, if you have an organtone or a tel ray, I'd love a point of reference, maybe some samples uploaded to the forum in the tel ray thread? Thanks!

Peter, Thanks - I'll drop you a line! Joshua Kern - testfiles (pulses) for measuring vintage gear curves (and instructions for using them) are available on the echotapper.nl site, would you be interested/willing in running the test tones through your adineko and posting the result to the forum? Cheers, Michael

Michael, For most of the vintage gear a testfile was put through it (see: http://www.echotapper.nl/tutorial/index.html) for the actual file pattern. Using a testfile is easy as it can be send around. I will check your module early next week. In the mean time, if you leave me your email address on grilmooqsi@farifluset.mailexpire.com we also could discuss it more indepth if you like. Note: the mailexpire email address is valid for 24 hours then it's gone.

Hi Peter, Cool to see you commenting as the etap2 was my inspiration for putting an actual EQ in the feedback path, and your excellent website was the source of my curves for the snapshots! I haven't actually had a chance to play with etap2 (I'm on a mac) but your user manual and specs were inspirational. I do have an echo question for you - where did you find your curves for the different echo models? And do you have any idea of the frequency response of a tel ray? Thanks! Michael

Michael, If you require specifics on echo's let me know. Also, the VST module eTAP2 available from echotapper.nl is filling-in another gap in the echoes department possible complimentary to yours! Peter www.echotapper.nl

Joshua, Lucky you! It would be great if you could make any suggestions on improvement based on your first hand experience, and/or send me some small sample files of the various modes/settings for reference. There's a forum thread on my tel-ray project, you could post them there: http://www.native-instruments.com:80/forum/showthread.php?t=63956&page=3 * Michael, Hey! Your echo devices are great, and full of interesting ideas, and clear construction - a real inspiration to me - it would be great to see you authoring echoes for the community again. With that in mind, you might be interested in this site: http://www.echotapper.nl/ ... as for the "variable delay" perhaps you'd like to take a crack at it? * Finally, a quick note - in my GUI building I made an annoying omission for the sake of appearance (duh!), You really need the "preamp level" knob (available on the "B" panel) to set the drive/out levels properly for the preamp section of the effect. I'll fix this in my next iteration, but in the meantime, tweak your "preamp level" on the back panel if you're setting drive/out. Sorry!

Looks very nice, Michael. Can´t wait to try it out. Didn´t know this kind of echo. I´m very glad you like my echos, I hope to find the time to contribute some more echos to the community.

Hello Mr. Barker, I have a Tel-Ray Ad-n-echo model 1001. If there is anything I can help with let me know. Good idea though...

Hi James, Glad you like it - I've been enjoying it (it'll do until I have a tel ray of my own!). I don't have a tel ray, let alone an 'organ tone' for reference - I've been working from recordings of tel ray devices - but I do have a version of this with a more blatant instance of "I want to be 122' piped into the echo signal path, with a stereo out. Sounds pretty nice - but not like a "variable delay" - so I pulled it out. I'll dig it up and see if I can get it into shape for you. Not an accurate emulation, but something fun to play with maybe. As an aside - I must admit, I intended this as a mono effect (because that's how I'd use it) but left the "stereo out" for "demo-ing" purposes.

Wow. This sounds amazing and unique (like a Tel Ray) and looks great as well. Excellent work. I don't suppose there's any chance for an emulation of Tel Ray's 'Organ Tone'? Regardless, thanks a ton!
