Keith Manners

Keith Manners is the person who is credited on several MIDI versions of Motorola ringtones between 2004 and 2009. While very little is known about him, it seems he did not directly work for/with Motorola, but was rather contracted by APM Music to create the MIDI arrangements, as Motorola's agreement with APM Music meant that both MP3s and MIDIs were provided. As APM Music also provided their music to other ringtone providers, it is also possible he created other MIDI covers for other companies.

There is also a person named Keith Manners who has created brass arrangements and original compositions for several brass bands, although it is not clear if this is the same person.
