i'm not from US, i'm from italy
I am not familiar with everything in the European market..there are territories for selling retail and products that you may get there..and not here..and vice versa also rebranded under different Brands names.A lot of older Alesis kits/design is sold as Millenium.
I also don't know if there is a local used market like Craigslist here in the US.
Check the
Drumshack in the UK..they carry new and used or 2nd hand drum gear..may have used E-Drum rack..they also carry the
Gibraltar SC-GEMC.. and show it mounted on a similar rack setup I was describing above.
*Alesis Compact Kit 7265 Voices...45 Preset Kits...100 Preset Songs (80 looped songs/20 fixed-length songs) and 5 User Kits
PYLEPRO PTED01215 Percussion Voices..128 GM Voices...25 Preset Drum Kits..100 Songs and 5 User Kits
SPECTRUM AIL 602 215 Voices, 20 Preset Kits, 100 Preset Songs and 10 User Kits..
The Spectrum is based on the Medeli DD305..the Alesis and Pyle are based on the..Medeli DD315..
Identical but different Firmware...like the Alesis Drum Kits..same modules different firmware.
The Voice DATA for the DD315 is double (16M bytes) the DD305 (8M bytes)
I couldn't find much info about the Spectrum other than old reviews showing it was sold in 2010 by
Spectrum Diversified which has nothing to do with musical gear.
The Pyle manual doesn't match the product description and is basically an earlier copy of the DD315 manual
"50 preset drum kits
260+ percussion voices and 128 GM voices, 16M bytes voice data
100 Pre-Loaded songs (includes 80 styles and 20 songs)"
Both of the manuals suggest an additional GM section.."and 128 GM Voices"..but I did not see a "GM mode" in any of the manuals and the Voice descriptions show a number of "GM" names ..probably should read "includes 128 GM Voices" as if there were additional.. the Voice counts would be closer to 400 using the numbers provided in the manuals.There are also 128 Backing Voices in General MIDI (Attached)
