Problem with K5M
Has anybody experienced the problem that can be heard in this recording? I started at c and went up a half step each time up to 2 octaves. http://f1.grp.yahoofs.com/v1/8HTCUA1Ujr4CnFQ-b3BnanwGDJ-FOuIccLTMNDenPwyO-KfE3rl\ QR_JDDWup4F8cDafSgFKFy3qRqZaOUL_dN7eK2RmGkmw/K5M%20Sample.mp3 https://soundcloud.com/shane-k/k5m-sample Both of these are the same recording. Thanks ------------------------------------

Audio demos?
Like I said before, I know that demo video and audio on the web are pretty scarce for the K5. Thank you for the few audio examples on this group page. That actually helped a lot! I have also listened to the old sales demo from 1987, as well as a few vague demos on Youtube. There's really not much out there, compared to other synths. So, do any of you know of any audio or video examples on the web that really show off what the K5 can do? Youtube? Soundcloud? Even music examples from a recording artist like Jan Hammer or Jean Michele Jarre where you can specifically hear it in-action? Thank you for all of your help! This seems like a great community. If I wind up getting a K5, I would love to help you support and show off this long lost synth! ------------------------------------

Re: Re: LED Backlight
Ok, so after looking at the K5 service manual, the LCD we have in the K5 should be a Toshiba TLC-711A-E0.
A little reading online seems to tell that the TLX-711A-E0 LCD module is an identical replacement and we have the datasheet here :
Which shows that the new panel from Futurlec would be a suitable replacement with LED backlight. Of course, the voltages aren't the same. The original EL backlight works at 130V 1kHz while the LED is working at 4.1V.
Most of the time, the inverter in the K5 dies before the EL backlight, due to cold solder joints in the epoxy-filled inverter (good luck trying to fix it).
But even if you spend around 20$ + shipping for a new inverter, the EL foil will often be very close to it's end of life, so you'll spend another 30$ +shipping to fix this.
As Mo just said, if you email backlightsonline.com, they'll have a replacement backlight foil for you. (Altough I don't know if it's LED or EL based.)
Now, the only two known inverters that are within specs for a new backlight are the NDL-205 and NDL-206 from JKL Components. The 205 is a little low on output voltage (90V) so it probably won't come out as bright as it should be. The 206 is a more suitable replacement (120V output), but seems to be a custom order everywhere I looked.
The LCD module at Futurlec sounds promising to me as LEDs have a much longer lifespan compared to EL backlights, and we could just replace the inverter by one or two resistors to get the 4.1V required. There is a blue on black version available as well if some would prefer
However, I haven't tried this particular LED-backlit LCD, but generally speaking, a fresh EL backlight provides a very uniform and bright display, while LEDs make bright spots all around the display. Another thing you'd lose is the good 'ol K5 whine coming from the inverter.
I'll probably give the LED display a try eventually and tell you if it's a viable option.
Cheers,
Antoine

www.backlightsonline.com these are replacement backlights. They replace the original backlight panel behind the lcd

My guess is it's either an LED backlight foil to replace the current EL one with the inverter, or it's a whole new LCD display.
I'm under the impression that this display might fit as a replacement :But haven't looked more into it. It's using an LED backlight and has the same physical dimensions if I remember correctly as I looked into it years ago, but it doesn't mean the controllers are compatible.
-- Antoine Deschênes2012/11/24 <maggooster-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>I'm interested in the LED back light option as well. Is it, possibly, just a matter of hooking up bright LEDs and placing them around the display?
Using duct tape, of course, to hold them in place ;)

LED Backlight

Considering a K5 - Need a little help!
I'm looking at maybe aquiring a K5 for my synth rig. I currently use an Ensoniq ASR-10, Roland Alpha Juno 1, Moog MG-1, and various VST synths. I'm building an ambient/space music live show, and I love sounds with radical timbre shifts, like FM and vector synthesis. I know that additive synthesis would give me a huge amount of versatility. The specs on the K5 look absolutely stunning! I think programming a complex board like that would actually be fun! The only problem I have is resources for how the thing actually sounds! I know now that Kawai's factory presets may not have been the best, and that it's one of the reasons why it was never popular, so I know not to be so quick to judge the sound on that. I've spent some time scouring the internet, and I dug up a few sound demo's on the web from Youtube, Soundcloud, and even the original Kawai audio demo from 1987, but all of these seem very limited. Also, reviews on Harmony Central and Sonic State are usually mixed. People either love it or hate it! So, maybe the community can help me out? How would you describe the K5 sound? I'm obviously not expecting an analog sound from a 1987 digital synth, but can it be fairly warm and punchy? I've heard a lot of demos from the Kawai K4, and that model seems to have a very warm digital filter. Is the K5's filter pretty much the same thing? Or does it have a totally different tone? Thank you so much for your help! ------------------------------------
