The company does not currently have to worry about piracy as they do hardware based modelling.
If they have a sustainable business that makes them happy and they have zero worries about someone stealing their IP then why change? I realise protection can be effective but it can never be 100% and, when it’s gone, it’s gone. You’re then relying on the honesty of customers which isn’t a business plan. They’re obviously making enough money to make the business work and indeed grow with new hardware whilst being able to afford to give free updates to customers who have zero chance of being pirates.
Also, if they were to make a full Kemper plugin it would have to be a fraction of the cost of the hardware. Whilst some folks would ‘need’ the hardware, some potential buyers would be happy with the plugin so you’d see a fall in sales of the hardware. Would this be overtaken by masses of sales of plugins, especially when some folks would inevitably wait for the crack?
They’re a business. If it was do-able with the team they have and the numbers looked favourable they’d do it. Who knows, still might but I’m not holding my breath for the above reasons.
I’d still like to see the plugin that controls the hardware Kemper at some point - it would be another great feature that adds value to their product and gives no risk of lost sales / piracy.
