“YAMAHA DX-1 Synthesizer with A/B cartridges Up for sale is my pristine YAMAHA DX-1 Synthesizer with A/B cartridges. I have owned this beautiful work of art for over 20 years and have not put many hours on overall on this uniquely distinctive and visually stunning keyboard.. It use to belong to a famous Boston based composer and due to my work and other issues I have not been able to put in the time that I desire to utilize this BEAST of perfection. I fill that someone else should benefit from the creative sound pallet that this instrument can inspire from. I have recently had my tech go over the machine and replace the battery and has a clean bill of health. The Keyboard will be costume crated and shipping quotes will be determined by zip code. I will consider shipping this instrument world wide but I do prefer to ship this within the United States. I currently reside in Arizona and I’m willing to drive up to 400 miles in any direction to meet someone to take delivery of this Keyboard as an option to not shipping it. ”

“This is a vintage Yamaha DX7 II FD FM synthesizer keyboard.
“needs a little love. 1 key is broken off. and 1 other key has light chipping underneath. As pictured it says it needs it’s RAM battery changed…I have done that already and if you do a factory reset the original patch library comes up just fine…sometimes booting it off and on it loses those patches and goes into “sine” wave mode where it’s all just sine wave oscillators to play and back to a battery mesaage.

“I do not have extensive knowledge about this device. From what I can tell, it is in good working condition. If you notice in photos 5 & 6 there are a few random keys that are not “up” like all of the others. I am not sure what this means, or how it happened, but I figured it was worth mentioning. Also includes an after market AC adapter that didn’t get pictured.”

“Hi,i have for sale a Yamaha D11 programable synthesizer that i am selling for spares and not currently working.The condition of the synth is fair but it does fire up fine.However there is a missing key and several keys are a little loose,one is also cracked.Currently there is no playing mode and i have changed the CMOS battery to aid its reset factory mode.I have pressed the edit,no 16 and 32 and then yes button but all i have managed to do after a couple of hours trying is to enter an edit mode.I can not currently get out of this mode at present.The illuminated screen has some fading didgits but all the buttons appear to work.The Pitch and Modulation wheels are all fine too.There are age related marks and scuff but i am sure it will come good to the right person.Can you bear in mind this is sold as not working so please take a look at the pictures to see the general condition.”
