Harmonix' Greg LoPiccolo said that the gameplay has been in the company's games all along, but it just took a while for them to present it in a way that people would grasp what it was about.
Speaking to GamesIndustry.biz, the project leader for Guitar Hero and Rock Band said that they put a lot of work into Frequency and Amplitude - which he considered somewhat ground-breaking concepts in their time.
"I remain really proud of them - I think they're great games - but the thing we learned from those games is that an abstract concept is very hard for people to get their heads around," he said.

A new Guitar Hero game looks set to be announced by Activision as Guitar Hero Mobile ads are appearing on Instagram out of the blue.
Should have been a console game, right now would have been a good time for a new Guitar Hero.
Time to revive all those popular franchises that are easy to monetize with micro transactions and nothing is easier than music games where they’ll charge you $5- 10 for 2- 5 songs.

CRKD and Gibson have teamed up to produce a completely new Guitar Controller for use in Rock Band, its successor Fortnite Festival, and Guitar Hero.
Phil Spencer talks candidly about missing out on both Destiny and Guitar Hero
So you're saying that Microsoft has missed out on so many huge gaming franchise in the last 25 years from GTA exclusivity to guitar hero and destiny it's just laughable they had so many misses
Best deal deal in gaming must be when Sony bought Insomniac for 229 million dollars. They made over 800 millions on Spiderman for the ps4 alone. Thats just crazy!
another Interview?
how is he the only one who loves the spotlight as much as he does lol
Let's not forget he also famously passed on Spider-man, Genshin Impact and GTA3.
However it's almost kind of cute how he can keep that sh1t-eating grin and say he's a 'no regrets' kind of guy, especially when you think how much just these 5 titles could have swung the world in Xbox's favour instead of Sonys.
How he's kept his job I don't know, he must sure be keeping Papa Nadella's shaft warm somehow.
"But, but Gamepass, he introduced that!!!"
Yes he did, and now look at Xbox, all it's exclusives are coming to Playstation now rendering the platform obsolete.
to me it will always be:
Amplitude > Rock Band/Guitar Hero, etc.
but i still love rock band.
