My latest keyboard is a 76-key Yamaha EX5. First I tried the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/61-76-key-version/dp/B0002CZTIE/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">61/76 key version</a>&nbsp;that I use on my Virus and Z1. The fit wasn't even close. I ordered this "88" key version and it fits perfectly.
